Abstract (en)

[origin: WO2019212453A1] Systems and methods for operating a power converter with a plurality of inverter blocks with silicon carbide MOSFETs are provided. A converter can include a plurality of inverter blocks. Each inverter block can include a plurality of switching devices. The plurality of switching devices can include one or more silicon carbide MOSFETs. A control method can include providing, by a control system, one or more gating commands to a first inverter block in the plurality of inverter blocks. The control method can further include implementing, by the control system, a gating command delay to generate a first delayed gating command based at least in part on the one or more gating commands. The control method can further include providing, by the control system, the first delayed gating command to a second inverter block in the plurality of inverter blocks.
