In this paper, a new Three-Level Simplified Neutral Point Clamped inverter with GaN-Si hybrid structure for motor drive applications is introduced. This topology allows the utilization of fast switching capability of new wide bandgap power devices with low blocking voltage together with conventional silicon power devices with high blocking voltage in one system. Thus, the advantages of fast switching power devices and multilevel inverter topologies are combined and the efficiency can be improved.
