Modular multilevel bundleThe ultimate solution for the fast and reliable prototyping of modular power converters
PowerTrench ModulesSemi-industrial prototyping building blocks
REALISTIC ARCHITECTUREExperiment at low voltage, while facing all the chal-lenges of the control of advanced power converters in realistic conditions using the PowerTrench modules.
These building blocks implement not only the power switches, but all the necessary measurements, protec-tions and signalling to mimic large power converters to help you identify the true control challenges, acceler-ate your developments and reach concrete and pub-lishable results in no time.
MODULAR CONSTRUCTIONWork with power hardware that is not only perfectly suited for your immediate developments, but also your next one and those after that.
With the PowerTrench modules, reconfiguring the con-verter topology can be done by simple changes in the board-to-board cabling and rack-level configuration. This way, there are practically no limitations in the con-verter topologies you imagine and test inside your lab-oratory.
BoomBox RCPThe ultimate tool for fast and reliable power electronics developments
TAILORED INPUTSThe BoomBox embeds software-independent pro-tections that block all outputs in case of any error within a few microseconds. This reliable mechanism is often very useful when the control software is not yet entirely stable and allows to work in real-life applica-tions with a complete peace of mind.
Besides, thanks to its flexible analog front-end – with high- or low-Z inputs, filters and gains – moving from one application to another can be done in minutes.
DEDICATED OPERATING SYSTEMSimple is beautiful, that’s the key guideline behind the BoomBox’s operating system! It contains just what is needed for protection, communication and real-time supervision.
By avoiding the usual burden of conventional operat-ing systems, sampling and interrupt frequencies up to 200 kHz can be achieved, which brings high perfor-mance controls within everyone’s reach, including for the most complex topologies.
The right size for every needScalable solutions for any application
Play with modules as you would PLAY WITH LEGOs, and place the elements in series or in parallel to build up any converter system in a scalable manner. Assemble modules into racks and racks into sys-tems to leverage even more scalability.
With the PowerTrench modules, there are practically no limitations to the converter topologies you can build in the laboratory, and there is certainly a solution for everyone’s need and ambition !
SCALABILITY may also be considered in the long run, starting with only a few cells and growing an experimental facility progressively over time.
Multiple power modulesA broad choice of building blocks for various types of applications
AIR-COOLED HALF-BRIDGE
WATER-COOLED HALF-BRIDGE
SEMI-INDUSTRIAL MODULESThe PowerTrench modules embed a half-bridge (i.e. phase-leg) of two power switches from IXYS semi-conductors, which can be freely selected among four possible types of devices. This allows various configu-rations, ranging from 600 VDC to 1200 VDC and 40–100 A depending on the switching frequency (LF- or MF-oriented).The modules also possess local desaturation detec-tion, as well as voltage and current sensors, hence facilitating a quick implementation.Two cooling variants are available, either using forced air cooling (80 W TDP) or water cooling (250W TDP).
TEACHING-ORIENTED MODULESThe reduced ratings (10–15 A and 200 V) of the smaller modules are targeted for proof-of-concept and teach-ing-oriented applications.Hence, in addition to the simultaneously available voltage and current measurements, the modules also possess over-voltage, over-current and over-tempera-ture protections, which can be directly programmed by the user within the independent onboard micro-controller.Due to their simple air-cooled design, these modules are mostly limited by the thermal power envelope, although powerful devices can be selected, allowing for surge power applications.

I/O EXTENSION MODEIn this mode, several control platforms are tightly linked to provide additional I/O capability while ensuring temporally-coherent signals between all boxes. The control software runs on a single device, which is the master controller. Applications with a high number of power switches and/or sensors are targeted (e.g. interleaved or multilevel topologies).
PARALLEL MODEIn this mode, multiple contol platforms are inter-connected to create a coordinated control system. Each box is running its own software on its own time basis, and is also simultaneously exchanging control variables with its neighbors. Casacded converters are typically targeted by this mode (e.g. back-to-back systems) but also systems that require redundancy.
MIXED MODEIn this mode, the platforms are interconnected using both I/O extension mode and parallel mode. This leads to possible configurations with up to hundreds of PWM outputs and analog inputs. Topologies with a high number of I/Os and a high interdependency are targeted by this mode, such as all kinds of multi-level converters (e.g. MMC, CHB, etc.).
