Abstract

The switching characterization of power devices is critical for improving the efficiency and reliability of power electronic converters. In this paper, the switching characteristics of silicon carbide (SiC) MOSFETs in a three-level active neutral-point-clamped (3L-ANPC) inverter are investigated. A parasitic model of the 3L-ANPC phase-leg is proposed first based on a design case and its ANSYS/Q3D simulation. Then, two typical commutation modes for ANPC inverters, namely the outer mode and the inner mode, are studied, and the separate switching loops and parasitic inductances are identified according to the parasitic model. Knowing this, double-pulse tests (DPTs) for each type of commutation are conducted. The differences in terms of switching characteristics and switching dissipations are fully revealed. The conclusion drawn can be utilized for developing the next-generation highly efficient and reliable SiC MOSFET based 3L-ANPC inverters.
