Title: Rotating switching strategy for power converters

Abstract

Systems and methods for operating a power converter with a plurality of inverter blocks with silicon carbide MOSFETs are provided. A DC to AC converter can include a plurality of inverter blocks. Each inverter block can include a plurality of switching devices. A control method can include identifying one of a plurality of switching patterns for operation of the inverter block for each inverter block. Each switching pattern can include a plurality of switching commands. The control method can further include controlling each inverter block based on the identified switching pattern for the inverter block. The control method can further include rotating the switching patterns among the plurality of inverter blocks.
