Abstract
Systems and methods for reducing switching losses in an electrical system in an aircraft are provided. In one example implementation, a method can include receiving DC power at an inverter of an electrical power system of an aircraft. The inverter can be a multiphase inverter having at least one bridge circuit for each output phase of the inverter. Each bridge circuit can include a plurality of switching elements. The method can include generating, by one or more control devices, a plurality of duty cycle commands for operation of the plurality of switching elements for each bridge circuit. The method can include operating, by the one or more control devices, the inverter in accordance with the plurality of duty cycle commands to generate a multiphase AC power output from the inverter. The plurality of duty cycle commands can be generated at least in part using a space vector modulation process.
