Review of Si IGBT and SiC MOSFET based on hybrid switch

SiC Hybrid switch (HyS) combines low conduction loss of Si IGBT and low switching loss of SiC MOSFET, and the cost is closer to that of Si IGBT. The promising high performances of HyS will bring considerable achievement in terms of enhancing power density of a converter system. By reviewing the gate drive pattern, gate drive hardware, current sharing, module design, converter design, and cost, this paper introduces state-of-the-art SiC HyS.
