Abstract
A SiC/Si hybrid switch (HyS) composed of a larger current IGBT and a smaller current MOSFET can provide higher cost performance. Previous research on the hybrid switch mostly focuses on reducing loss and balancing junction temperature through different control strategies, neglecting the reliability issue caused by the load current exceeding the safe operating area (SOA) of SiC MOSFET with a lower current rating. In addition, it remains an unsolved issue that how to design gate resistances for a Si/SiC HyS. This manuscript investigates the impact of gate resistances on switching-on behaviors of a Si/SiC HyS in a double pulse test. Furthermore, the tradeoff between switching loss and the device reliability can be used as a reference for selecting the switching-on gate resistance of a hybrid switch.
