Inverters

Our modular inverter kit is a versatile and highly customizable solution.

We can tailor our inverters towards nominal voltages of 48V, 400V or 800V, naming the solution IV1 through to IV5, accordingly.

The inverter’s mechatronic design is highly customizable to different applications, ranging from 2-wheelers to heavy duty trucks. It can operate with MOSFET, IGBT-based or SiC-based power modules.

All our inverters use a unified digital platform, which limits the complexity in software version management. Current levels can be up to 400Arms continuous and 800Arms peak.
