A hybrid switch composed from a silicon (Si) IGBT and a silicon carbide (SiC) MOSFET may be a possibility to reach lower losses within resonant converters. In addition, the desaturation of the IGBT before switching-off may be beneficial. This approach is investigated with a supplementary inductor within the IGBT path and a corresponding modified desaturation circuit.
