Power Electronics? Power electronics = High Power
Utilities Relates to control of flow of current. Scope of power electronics: milliwamtts
⇒ Gigawatts Main motive is efficiency. Some power electronics device
Mercury arc tube Rectifiers, etc.
Power devices requirements High switching speed Minimum losses High on state current High off state voltage Low noise
Power Devices
Power Device
s
Diodes
FETs
IGBT
Transistors
Motor drives? It is device to control:
Speed Direction Torque
Motor Drives Component: Diodes Thyristor family devices
Over all optimizes performance.

Conclusion Thus, the operation of any Drive can be
studied by observing it’s basic circuit. The new inroads into development of an
IC chip instead of a bulky drive circuit has improved cost- efficiency of the system.
