SiC half bridge power module for powerful inverters

PEB8038 half bridge modules contain two power semiconductors (Silicon Carbide MOSFETs) as well as gate drive and measurement circuits.

They enable engineers to rapidly implement powerful inverters to validate converter control techniques in realistic conditions. These modules are often used for 230/400VAC applications such as in experimental microgrids or similar applications.

Designed for research applications

Onboard protection mechanisms

As with all imperix power modules, PEB8038 half bridge modules embed protection mechanisms such as over-current/voltage detection, which block the SiC half-bridge in case of hazardous behavior and thus ensure that its capabilities are never exceeded.

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

Application examples of SiC power modules

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

PEB8038   VS  previous generation

Featuring powerful Silicon Carbide MOSFETs, PEB8038 modules offer the largest figure of merit among imperix power modules.

For instance, the new PEB8038 module can deliver above 8kW per phase into a 230/400V three-phase load. This corresponds to a total of 24kW for a three-phase inverter!

This level of performance is linked to the very low on-state resistance of the power semiconductors (RDS,on = 20mΩ). On the other hand, these modules are not optimized for fast switching operation; their typical operating frequency range is limited to 10-30kHz.

PEB8038   VS  previous generation

Reduced switching losses

PEB8038 offers slightly lower switching losses than the previous PEB8032 module. This broadens the range of their possible applications.

Reduced conduction losses

A drastic reduction of conduction losses can be observed between PEB8032 and PEB8038, with over 30% less energy lost during conduction!

Additional benefits for power electronic research

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


With these building blocks, power inverters or any converter topology can be built rapidly. 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 modules are sufficiently powerful to handle a few kW per phase. This makes them a perfect choice for demanding laboratory applications, microgrid inverters or pilot/demonstration systems.


PEB modules 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.

Power module accessories

Rack-mounting equipment

Imperix SiC half-bridge modules are power electronic building blocks, which are best assembled within rack-mountable frames or enclosures. This guarantees the highest flexibility, thanks to the modular nature of the power converter modules.
