Ready-to-use SiC power modules
Embedded functions and capabilities
The PEB8024 SiC-based phase-leg modules are truly ready-to-use power electronic building blocks featuring:
- SiC MOSFET phase-leg (two power semiconductors)
- DC bus capacitors
- Current and voltage sensors (usable simultaneously)
- Integrated gate drivers
- Onboard logic and protection (desaturation, voltage, current, temperature, PSU)
- Speed regulated cooling fan (120 W TDP)
Designed for R&D applications
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.

Silicon Carbide module specifications
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
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.
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.
Versatile
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.
Easy-to-use
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.
Powerful
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.
Robust
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.
Accessories for SiC power modules
Rack-mounting equipment
Imperix SiC power modules are power electronic building blocks that are best assembled within rack-mountable frames or enclosures. This guarantees the highest flexibility, thanks to the modular nature of the power converter modules.
PEB modules can be mounted within open rack-mountable frames. As such, modules remain easily accessible and can be easily put in (or taken out) of the chassis.
Imperix power modules can also be placed within enclosures that make use of 4mm laboratory safety plugs. This guarantees that no dangerous voltage can ever be reached.
For those interested to have a first configuration that is fully ready-to-use, imperix offers a standard box with inductors and LC filters. Components have reasonable, but fixed values.
