Ferdinand-Braun-Institut leads HiPoSwitch project to improve the power performance of energy converters

The Ferdinand-Braun-Institut has launched a new EU project that aims at creating more compact and powerful energy converters for use in information and communication technology as well as solar inverter technology. The HiPoSwitch project's activities cover the whole value added chain, from GaN power device development to industrial application.

This is due to the lower on-state resistance of GaN power transistors, combined with considerably reduced in- and output capacitances. The increase of switching frequency has also consequences for the passive components as the volume of inductors, current transformers and capacitors can be reduced. The whole assembly becomes smaller and morelight weight. The transistors will be built up on cost-efficient silicon substrates which will make them more attractive from an economic point of view. In the long run, they will combine improved technical properties with comparably low costs.
