Onboard protection mechanisms

As with other imperix power modules, each SiC power module embeds protection mechanisms, such as over-current/voltage detection, which block the power module in case of hazardous behavior and thus ensure that its capabilities are never exceeded.

Combined with the additional adjustable protections of our programmable controller, imperix power modules are the ultimate solution for safe and efficient converter prototyping in both teaching and research applications.

Application examples of SiC power modules

Most power converter topologies can be built using elementary phase-legs, which can be considered as the basic building blocks of power electronic systems. Basic use case scenarios built with PEB power modules include single-phase inverters and three-phase inverters, as well as isolated or non-isolated DC/DC converters.

Superior switching performance 

PEB8024   VS  previous generation

Thanks to state-of-the-art Silicon Carbide MOSFETs, the PEB8024 power modules enable faster switching frequencies than our previous phase-leg modules, while guaranteeing lower losses. These modules allow building power converters with superior harmonic performance, more compact passives, and thus increased power density.

In addition, the embedded current sensor features a high measurement bandwidth, allowing to precisely sense the output currents, enabling the validation of fast closed-loop control techniques.

For higher current capabilities, engineers are recommended to consider the PEB8038 module, which embeds larger (but then slower) semiconductors.

PEB8024   VS  previous generation

Improved switching performance of the new SiC power modules.
Reduced switching losses

Silicon Carbide modules offer up to 10x lower switching losses when compared to Silicon, even with fast IGBTs such as on the previous PEB8032 modules.

Improved maximum switching frequency of the new phase-leg modules.
Faster switching frequency

At the module level, PEB8024 are specified as 4x faster than the previous generation, with both superior switching speed and efficiency !

Additional benefits for power electronic research

Our Silicon Carbide modules (SiC) – similarly to our Silicon-based modules – offer an excellent trade-off between ease of use and suitability to multiple and various applications. They are ideally suited for rapid control prototyping applications, where the quick implementation of the power stage is essential.


With these building blocks, DC/AC inverters or any converter topology can be built in the blink of an eye. What’s more, power modules can be reused among multiple projects to save time and money.


The modules contain everything needed to start working right away (sensors, logic, cooling,…). Combined with the B-Box family of controllers, they form a truly plug-and-play solution.


The PEB power converter modules are sufficiently powerful to handle a few kW per phase. This makes them a perfect choice for demanding laboratory applications or pilot /demonstration systems.


The PEB modules are well protected and can be safely put in the hands of inexperienced engineers. This is ideal for teaching or student projects, or simply for those who enjoy the related peace of mind.
