Abstract :
SiC devices such as MOSFETs and BJTs have proven themselves to be contenders to improve the efficiency of resonant converters. The losses of the full-bridge inverter are well below 1% of the rated power at switching frequencies up to 200 kHz, making it possible to reach even higher frequencies. An experimental setup is built and two different full-bridge inverters are tested. One is built with SiC MOSFETs and no additional anti-parallel diodes and one with SiC BJTs and SiC Schottky diodes.
