Traction Inverter

Efficient drive solutions
for electromobility

A traction inverter converts the battery’s DC voltage into precisely controlled AC voltage for the electric motor. It defines the vehicle’s efficiency, dynamics, and range. Modern inverters rely on SiC or IGBT technology to minimize switching losses and manage thermal stress. Compact designs, reliable gate drivers, and high-performance thermal interface materials are key to achieving these goals. Together, we develop solutions that meet your performance and safety requirements - from prototyping to series production.

We’ve compiled our most relevant products for traction inverters here for your convenience.
