Abstract
A power supply for use with an N-phase multiphase machine comprises an inverter, an isolation stage and a rectifier The inverter is configured to be coupled to a DC power supply and includes N machine switch circuits for providing N-phase machine drive signals to the multiphase machine in response to N-phase machine drive commands, and an auxiliary switch circuit for providing an auxiliary AC output in response to auxiliary control commands. The isolation stage coupled to the auxiliary switch circuit and generates an isolated AC output. The rectifier is coupled to the isolation stage to rectify the isolated AC output and provide an auxiliary DC supply output.
