Abstract
A power converter control device performs PWM control for power converters which respectively supply power to a plurality of winding groups of a multiplex-winding electric motor including the plurality of winding groups, the power converter control device including a PWM control unit which performs control while selectively switching among an asynchronous PWM control mode using a carrier not synchronized with voltage commands for respective winding groups and both or one of a first synchronous PWM control mode in which voltage commands for respective winding groups are subjected to PWM control using a carrier synchronized with a voltage command for a specific winding group, and a second synchronous PWM control mode in which voltage commands for respective winding groups are subjected to PWM control using respective carriers synchronized with the respective voltage commands.
