NOTES :OVERALL SCHEMATIC OF POWER SUPPLIES

The power supply to this appliance is located on a dedicated Power SupplyBoard.

It essentially consists of two parts:- the FROSIN power supply, which delivers permanent voltages (control

power supply) as well as switched voltages for any signal processing carried outon the main board, the scaler board, and optionally, the DVD board.

- the resonant power supply which supplies switched VSSIN voltages forthe inverter board (specific power supply circuit for backlighting) as well as +/_UAfor the audio board.

For models that draw a lot of power (27" screen diagonal or bigger), a dynamicpower factor correction circuit is inserted between the rectified mains voltage andthe resonant PS so as to reduce cos phi and the harmonics reinjected into themains circuit.

The IR001 microcontroller located on the main board controls the standby outputvia the PO line. The latter provides switching for the 20 Volts generated by theFrosin power supply, and this voltage in turn activates three other voltages (10V,6V, 4V). Lastly, the 4V voltage starts up the resonant power supply.

The mains voltage is monitored by the microcontroller via the FROSIN powersupply and the INF_POW_FAIL line.

The Genesis circuit on the scaler board controls the start-up of the power supplyinverter via the V On/Off line and controls backlighting brilliance via the SCV briline.

quicker restart), and DP227 provides protection in cases of overvoltage by goingshort-circuit if this happens (disappearance of control current on TP220).

Four unswitched voltages are developed on the secondary:- 33 Volts for the tuner power supply. - 20.5 Volts.- 10.5 Volts powering a 5V regulator for supplying the control voltage

(5VSTBY).- 6.5 Volts, chosen for the secondary regulation; this is the origin of

3.3VSTBY.

Secondary regulation makes use of an opto-coupler (IP251) in series withregulation circuit TL431 (IP261). A fraction of the 6.5V applied to IP261 via adivider bridge (RP261/RP462) is taken and compared with the internal 2.5 Voltreference. Any variation in the 6.5 Volts will therefore tend to modulate the currentin the opto-coupler, and consequently, the instant when TP222 is switched andTP220 is blocked.An acquisition mode is provided by the use of transistor TP261. When the baseof the latter is released by the AQR line leading from pin 113 of IR001, TP261applies a 10.5V image (via DP261) to the regulator input, thus ensuring regulationof this voltage also.In the event of overload of the 6.5 Volts, a protection system short circuits theregulator and saturates the opto-coupler, thus temporarily blocking the choppingtransistor.

NOTES :

THE FROSIN POWER SUPPLY

This power supply, whose concept is in common use in the Group's products,generates the voltages required for standby mode and also delivers switchedvoltages for any "small signal" processing located on other boards.

A mains voltage of between 190VAC and 264VAC is rectified by theDP252/253/254/255 bridge, filtered by condensers CP258/259, then applied inparallel to transformer LP253 in the Frosin power supply and the push-pulltransformer in the resonant power supply (RAW_B+). The MOSFET transistorLP220 and the condenser CP220, in series with the primary of LP253, determinethe primary current. The latter is kept in check by resistance RP220.

The start-up current comes from a single mains phase via resistances RP257and RP 258, via condenser CP225, and via driver transistor TP495. This will onlyswitch when there is a charge of roughly 9 Volts or more coming from CP225,using the threshold effect of zener diode DP493, to ensure clean switching of theMOSFET transistor. Once the power supply is started up, the charge from CP225is obtained from self-powering (winding 6/8 and diodes DP225/226).The on/off switch does not act directly on the mains voltage but simply cuts offthe control current to the MOSFET transistor (connector BP253).

Chopping transistor TP220 is blocked by transistors TP222/223 (on/off circuit),which short-circuit the gate/source space when they are switched. This worksthrough the combined effect of primary current measurement (RP220 andRP231), of regulation from the opto-coupler (IP251), and of the auxiliary circuitsvia resistances RP238, RP293, and RP241:

- RP238 and condensers CP239/438 set the minimum saturation time forTP220.

- DP237 and CP237 time the new saturation of TP220, to limit dissipationby switching.

- CP240 and DP240 correspond to the soft-start and mainscompensation circuits.

Zener diode DP233 protects the gate/source space in TP220, DP230 blocks thesecondary regulation action when the charge on CP225 is too weak (promotes a

NOTES

SECONDARY SWITCHING ON THE FROSIN POWER SUPPLY

The order to quit standby mode is given from pin 87 of microcontroller IR001 andtransmitted via transistor TR198 and connecters BP001 and BP220A. Theresulting high state on line PO saturates transistors TP407 and TP205 andswitches the 20V voltage when above 20.5V. This voltage will be used in theSCART section but first and foremost it is behind the switching of three othervoltages:

- 10V obtained from the 10.5V voltage through the intermediary ofMOSFET TP204. This voltage supplies 9V and 8V for general audio and videoprocessing on the signal board.

- 6V and 4V via the IP203 and TP203 regulation circuit. These 6 Voltssupply several boards, in particular the 1H/2H IV100 converter on the signalboard. The 4 Volts are intended for the scaler board and starting up the resonantpower supply.

Two other unswitched voltages are also regulated:- 5VSTBY obtained from the 10.5V line by a similar stage to that used in

the 6V and 4V: divider bridge RP415/416 compares a fraction of the outputvoltage with the internal 2.5V reference in regulation circuit IP202, consequentlymodulating the gate voltage of MOSFET TP202.

- 3.3VSTBY obtained from the 6.5V via a regulator assembly which is areplica of the one described above (TP201/IP201).These two voltages are clearly intended for control.

NOTES :FROSIN POWER SUPPLY PROTECTION CIRCUITS

There is a first safety measure associated with overvoltage, which for examplecould happen because of a cut-off in secondary regulation. As a reminder, theprimary voltage generated by self-powering and applied to condenser CP225 inthis case will also increase. When it reaches 27V it will be limited by zener diodeDP227, whose current starts rising. Beyond a certain threshold, the zener short-circuits, thus removing the control current from chopping transistor TP220.

The second protection system is related to possible overloading or short-circuiting of the 6.5V voltage.At start-up, when secondary voltages are still developing, the time constantRP472/CP271 times the polarisation of transistor TP271, whose base is thenshort-circuited by the conduction of circuit IP271. When the voltage of the 6.5Vline exceeds 3.3V, the reference input of IP271 tends to exceed 2.5V via dividerbridge RP475/476, thus leading to increased conduction in this component andthe continued blocking of TP271. Consequently, in normal working conditions thecurrent in the opto-coupler is controlled solely by regulation from IP261.Now let's assume heavy overloading on the 6.5V line causes this voltage tocollapse below 3.3V. IP271 will then block, thus releasing the polarisation andsaturation of transistor TP271, which in turn will saturate the opto-coupler. Thechopping transistor is blocked this time by on/off circuit TP222/223 and the powersupply closes down.

This triangular signal is then shaped by the logic stages to control the push-pulloutput, with alternate saturation of TP321 on the up ramp and TP322 on the downramp, condenser CP325 being jointly used with the integrated bootstrapassembly to ensure clean saturation of TP322.

Maximum energy will be transmitted when the control frequency is the resonantfrequency of the primary circuit on transformer LP300 and condensers CP321and CP322, because the load impedance is then lower and the peak currentreaches a maximum value. Increasing the control frequency will consequentlyresult in the lowering of this peak current and thus a reduction in transmittedenergy. Since the control frequency is related to the overall resistance connected to pin4, modulating the conduction of the opto-coupler will give rise to a modification inthe oscillator frequency and thus control the energy transmitted.

Secondary voltage VSSIN is regulated by comparing it via a divider bridge(RP553, RP554) with the internal reference (2.5 Volts) on regulation circuit IP351.When the charge on this line increases, the voltage tends to drop as does thecurrent in the opto-coupler through the action of IP351. The overall resistanceseen from pin 4 therefore increases and reduces the frequency of the oscillatorand the control, which approaches that of resonating circuitLP300/CP321/CP322. The consequence of this, as explained above, is anincrease in transmitted energy.

NOTES :

RESONANT POWER SUPPLY

This second part of the power board supplies energy to the LCD panel in orderto provide power to the backlighting (inverter board) in the form of the voltageVSSIN (19 Volts); it also delivers symmetric voltages +/-UA (+/- 15 Volts) to theaudio power stage.

The core of the primary circuit is the integrated circuit ST L6598, which is adaptedto control an AC/DC converter that uses the principles of resonance and of a half-bridge configuration. In the final stage it comprises two drivers which alternatelyswitch one of two MOSFET transistors. The resonance circuit, which consists ofthe transformer primary and two condensers in series, is connected between theground and the common point of these two transistors.

The power supply source for this circuit is the primary of transformer LP253(V_PRI of the FROSIN stage), rectified by diode DP301 and switched bytransistor TP302.The start-up command signal is the 4 Volts from the FROSIN power supply, thisvoltage being switched by the micro-controller (PO). It saturates opto-couplerIP302, which blocks transistor TP303, thus releasing the polarisation of MOSFETTP302. On the gate of the latter, regulation circuit IP303 coupled with dividerbridge RP503/504 sets voltage Vs (pin 12 of IP300) to roughly 12 Volts (10.7Volts being the start-up voltage).

The oscillator incorporated into this circuit generates triangular waves whosefrequency is determined by the charging and discharging cycles of condenserCP516 (pin 3). The are the effect of currents Ifstart, Ifmin, and the charge on soft-start condenser CP315 (pin 1). Ifstart is linked to RP517 (Ifstart = Vref / RP517with Vref = 2V); Ifmin depends on RP511, RP512, and conduction in opto-couplerIP310.During the first instants of start-up, frequency is a function of the sum of currentsIfmin and Ifstart; then as the latter drops away with the effect of the charge onCP315 (soft start), the frequency does likewise and becomesfmin = 1.41/(RP511 x CP516) = 53kHz (with IP310 blocked).To sum all this up, RP511, RP517, and CP516 set the start-up frequency toroughly 100kHz. This then decreases with the soft start (~= 750msec) and dropsbelow 53kHz to settle down at a value that depends on secondary regulation(conduction in IP310).

NOTES :SECONDARIES AND PROTECTION OF THE RESONANT POWER SUPPLY

Voltage VSSIN (24 Volts), used for backlighting, is obtained by centre tap dualrectification (double diode DP381), whereas rectifier bridge DP371/372,DP391/392 generates symmetrical voltages +/_ UA for the audio power stage (+/-14 Volts).

A first protection system detects overvoltages on VSSIN via zener DP361 andtransistor TP361. If ever this voltage exceeds 25 Volts, the transistor will saturateand will short circuit opto-coupler IP302, temporarily taking away the powersupply to circuit IP300.A second protection system detects any secondary overloads by checking theprimary current. An image of is this picked up on resistance RP328 and appliedto the non-inverting input of the amplifier built into IP300 (pin 7), then comparedwith a reference voltage of 450mV (Vs and RP515/516). In the event of thisgoing over the mark (peak current more than 4.5A), pin 5 changes to the highstate and activates the comparator (pin 8), which causes the oscillator to stopand blocks the two MOSFET transistors.

NOTES :DYNAMIC POWER FACTOR CORRECTION (PFC) CIRCUIT CONCEPT.

Screens measuring 27 inches or more consume large amounts of power, makingpower factor correction necessary (PFC) in order to restrict the generation ofharmonics in the mains. A simple rectification circuit draws energy from the mainsonly when the instantaneous alternating voltage exceeds the charge voltage onthe filter head condenser. This takes place at values close to the peak voltage ofeach half-cycle; the result is current spikes whose shape is a long way from thedesired sinusoid (see diagram on left).

In order to achieve this aim, an inductance is fitted between the rectifier bridgeand the filtering condenser. The mean current of this inductance must besinusoidal and in phase with the rectified voltage. To achieve this, a powertransistor Q, controlled at a frequency higher than the mains frequency, chops therectified unfiltered voltage across this inductance. The frequency or the cyclicratio must be proportional to this rectified voltage so as to modulate the peakcurrent following a sinusoidal wave envelope (see diagram on right).

When the transistor is blocked, the induced voltage at the terminals of thisinductance is inversed, unblocking diode D, which supplies power to filteringcondenser C and to the standard converter.

Condenser CP711 (pin 12) determines the soft start criteria for the stage so asto limit peak current in the chopping transistor when establishing the voltageRaw_B+. The TP321 command appears when there is a voltage of 1.5V or moreon pin 12. This condenser is discharged each time the overvoltage (pin 3) orundervoltage (pin 19) safety system is activated.

As far as protection goes, three parameters are controlled in this stage:

- the minimum supply voltage on pin 19 of circuit L4981B. This voltage'sthreshold value of 10.1V is set by resistances RP844 and RP844 (pin 15). Whenthe threshold is reached, the circuit switches to standby mode, blocking thechopping transistor and discharging the soft start condenser

- the maximum output voltage via pin 3. This is set to 426 Volts by dividerbridge RP826/827/828, RP831 and the internal 5.1V reference. In the event ofovershooting, there are the same consequences as with the previous protection

- the peak current in inductance PFC200 measured by resistance RP723is applied to pin 2 via divider bridge RP814/RP847. In the event of an currentoverload, the voltage on pin 2, normally negative, reaches 0V and the choppingtransistor is immediately blocked.

NOTES :

POWER FACTOR CORRECTION CIRCUIT.

As previously explained, the power factor correction circuit reduces the level ofharmonics reinjected into the mains circuit by the power supply. It alsocontributes to regulating the voltage generated at the terminals of the filteringcondenser (370 Volts), thereby facilitating the work of the downstream powersupplies.

Control of this stage is provided by an L4981B circuit from ST. Its power supplyis obtained from the switched 4 Volts of the Frosin power supply. Opto-couplerIP302 transmits commands to the IP751/ TP751 primary regulation circuit viatransistor TP752. The resulting voltage (approx. 12V) supplies the input Vcc topin 19 of the circuit and activates a second regulation circuit, IP303/TP302, usedfor starting up the resonant power supply.Divider bridge RP844/RP843 uses the voltage applied to pin 15 to set hysteresisthresholds on the internal power supply of 12V for Vcc on and 10.1V for Vcc off.A reference voltage is available on pin 11 (5.1 Volts).The 45kHz frequency of the internal oscillator is set by resistance RP812 (pin17) and condenser CP812 (pin 18).

The cyclic ratio of the chopping transistor control signal must be inverselyproportional to the rectified input voltage, i.e., must vary sinusoidally. The currentpicked up at the output of the rectifier bridge by resistances RP807/808/809 andapplied to the input on pin 4 supplies the required reference. ResistancesRP801/802/803 form a filter in conjunction with components CP803/CP804 andRP804/806, supplying data that is proportional to the RMS mains voltage in orderto take account of any variations in the latter (pin 7). Lastly, the output voltage ispicked up by divider bridge RP832/833/834/837/839 and applied to the erroramplifier located between pins 13 and 14.These 3 pieces of data are then associated through a multiplier. The resultingcurrent (pin 8) is added to the image of the inductance current (RP723) viaresistance RP813 then applied to the non-inverting input of the error amplifier.The circuit located between pins 5 and 9 sets the gain for this stage.The CA-OUT signal available on pin 5 is then compared with the sawtoothoscillator wave in the PWM stage to supply a variable cyclic ratio that controlschopping transistor TP321 via the logic and driver stages and via pin 20.

POWER SUPPLIES TO IR001

These come from the voltages 5V_STBY and 3V3_STBY generated by the Frosinpower supply. A voltage of 1V8_UP, obtained from 3V3_STBY and regulator IP005,supplies the CPU of IR001.

IR001 CLOCK

A VCO/PLL assembly internal to IR001 clocks the microcontroller. The QR0018MHz quartz timer acts as the reference for this loop. The VCO working frequencyis 72MHz when running.

IR001 RESET

Integrated circuit IR004 coupled with condenser CR043 generates the reset signal.Pin 108 receives the RESET information.

IR001 HALT

A mains cut-off detection stage enables the TV set configuration to be saved if everthe mains voltage drops. Rectification and filtering of the voltage that is induced inpins 13/14 of LP253 by DP247 and CP247 gives a voltage in the region of –40V.Next, transistors TR061 and TR062 are blocked and pin 74 of IR001 goes to 0. Ifthe mains voltage drops below 140VAC, transistors TR061 and TR062 saturate.Pin 74 on IR001 changes to the high state (> 4V) and a back-up routine is triggered.Furthermore, because transistor TR060 is saturated, audio muting is effected.Once powered up, if pin 74 on IR001 is at 5V, the appliance remains on standbyand fault code 63 is stored in the EPROM.

Circuit IA001, MSP3411G lies at the core of this processing. It is driven by a18.432MHz clock and is controlled via bus I2C2 by control circuit IR001. The latteris also responsible for reset pin 21 on IA001.

This circuit- demodulates the FM audio intercarriers- demodulates NICAM audio- switches the various analogue audio sources for the peritel outputs- performs ADC on the various audio sources- corrects these digital audio signals (tone, pseudo-stereo, spatial stereo,

volume, Dolby virtual, etc.)- performs DACE

L/R POWER AMPLIFICATION

Power amplification takes place in circuit IS200 (TDA 7490). This is a D-classstereo amplifier that enables some 2 x 15 Watts of power (THD=1%) to be achievedwith the minimum dissipation commensurate with the narrowness of the listeningspace.The +/_ 14Volt power supply obtained from the resonant power supply is applied topins 2 and 4 on IS200.

The left and right signals generated by the Main Board are applied to the pin 10 and16 inputs. In the event of a mains power cut, the Power Good (PG) signal saturatestransistors TS207/208 and TS203/204, thereby short-circuiting the inputs to groundto avoid rattling the loudspeaker cones.

Because of its threshold, the voltage on pin 6 provides control over the circuit'sstandby, mute, and ON modes- through TS202, the audio_stby command sets the voltage to less than 0.7V for

standby mode- through TS201 and diodes DS203/DS205, the L/R_MUTE and MASTER_MUTE

lines generate a voltage of between 1.7V and 2.5V for mute mode- by blocking transistors TS201 and TS202, the 5V_V line brings this pin to a

potential of between 4V and 5V for ON mode.

For each channel, a 2.5 gain preamplifier precedes an integrator stage whoseexternal circuit is connected across pins 9/7 and 19/17. The signal obtained is thenapplied to the pulse width modulator (PMW) stage, synchronised to the masteroscillator. The frequency of the latter is linked to components CS232 and RS209(pin 8) for a typical value of 200kHz. We can observe the triangular signals on pins11 and 15.Items CS213 and CS218 are bootstrap condensers for the final stages, whereasthe counter-reaction circuit is comprised of resistances RS226/RS204 andRS227/RS213.Condensers CS001 and CS006 integrate the signals for application to theloudspeakers.

Switch SS001 enables changeover between built-in and external loudspeakers andhas a contact that informs the microcontroller via expander IR006, allowing this tolimit power to 2 x 5W for the internal left and right channels and to 10W for theinternal bass channel.

An IS100 (MC33079) amplifier delivers variable levels to two RCA (BS003) socketsfor external amplification that remains under the control of the TV set.

BASS POWER AMPLIFICATION

A second TDA7490 (IS500) is used for reproducing bass sounds. Its two channelsare used in a bridge configuration (the loudspeaker is connected across the twooutputs), thereby doubling the power of this monophonic channel. To do so theinverting input (pin 19) of the second integrator is linked through resistance RS510to that of the first integrator (pin 7), whereas the input of the second preamplifier isgrounded through condenser CS581 (pin 18).

The subwoofer signal generated by the Main Board is applied to input pin 10 onIS500. In the event of a mains power cut, the Power Good (PG) signal saturatestransistors TS207/208 and TS501, thereby short-circuiting the input to ground so asto avoid rattling the loudspeaker cones.

Because of its threshold, the voltage on pin 6 provides control over the circuit'sstandby, mute, and ON modes- through TS504, the audio_stby command sets the voltage to less than 0.7V for

standby mode- through TS502 and diodes DS204/DS201, the SUBMUTE and MASTER_MUTE

lines generate a voltage of between 1.7V and 2.5V for mute mode- by blocking transistors TS502 and TS504, the 5V_V line brings this pin to a

potential of between 4V and 5V for ON mode.

The oscillator in IS500 is synchronised to that of IS200 via transistor TS503 to avoidany beat phenomena.

A third amplifier built into IS100 (MC33079), along with the variable level subwoofersignal, completes the left and right outputs described on the previous page.
