DC/DC Converters

We provide custom specific DC-DC Converters for automotive, air craft and stationary applications. Research starts on basic level switching behavior of classic silicon and modern wide band gap SiC and GaN Devices. With highly integrated custom passive components from film and ceramic capacitors over gapped and coupled inductors to modern 3D aluminum laser sintered cooling solutions we create converters from 1 Watt to 1 Megawatt.

A and B-Sample Prototypes

Zero Series Converters starting from 1 Unit
