IGBT module for powerful inverters and low-voltage applications

PEB4050 IGBT power modules contain two Silicon IGBTs power semiconductors as well as gate drive and current/voltage measurements.

They are ideal for building grid-tied inverters under 110VAC voltage but are also applicable to all sorts of power converter topologies.

Notably, thanks to their high current ratings, PEB4050 power modules can be very helpful with battery charging and related DC applications.

IGBT Power module for the laboratory

Onboard protection mechanisms

As with all imperix power modules, the PEB4050 IGBT power module embeds protection mechanisms, such as over-current/voltage detection, which block the IGBT phase-leg in case of hazardous behavior and thus ensure that its capabilities are never exceeded.

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

System-level integration

A modular approach for building power converter prototypes

Possible mechanical integration of several IGBT half-bridge modules.

  • 3x PEB4050 IGBT power modules
  • 1x rack-mountable open chassis

Imperix  power modules are easy to assemble together

When used to build power inverters, PEB4050 IGBT power modules are ideally suited for 120/210VAC applications, as commonly found in North America and other countries with 60Hz grid frequency. In such cases, a DC bus voltage of 400V is indeed sufficient.

  • Interleaved DC/DC converters
  • 120VAC grid-connected inverters
  • Variable-speed drives
  • Frequency converters
  • Soft-switched converters
  • Modular multilevel converters
  • etc.

IGBT-based power converters

Application examples of IGBT 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 modules include single-phase inverters and three-phase inverters, as well as isolated or non-isolated DC/DC converters.

New IGBT power module

A powerful IGBT half bridge

PEB4050   VS  previous generation

Based on state-of-the-art IGBT semiconductors, the new PEBs enable faster switching frequencies than our previous IGBT power modules, while guaranteeing lower losses.

The new 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.

PEB4050   VS  previous generation

Improved switching performance of the new IGBT power module.
Reduced switching losses

PEB4050 offers about half the switching losses of the previous PEB4046 module. This broadens the range of their possible applications.

Improved conduction performance of the new IGBT power modules.
Reduced conduction losses

A drastic reduction of conduction losses can be observed between PEB4046 and PEB4050, with over 30% less energy lost during conduction!

Modular building blocks

Benefits for power electronic research

Our Silicon-based IGBT power modules – similarly to our Silicon Carbide (SiC), MOSFET-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 in the blink of an eye. What’s more, power modules can be reused among multiple projects.


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


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


IGBT modules are well protected and can be safely put in the hands of inexperienced engineers. This is ideal for teaching or student projects, or even classroom applications.
