POWER CONVERTER CONTROL DEVICE

WIPO Patent Application WO/2019/106777

A1

The purpose of the present invention is to obtain a power converter control device that is capable of controlling a power converter that supplies power to a multi-winding motor and stably driving the multi-winding motor. This power converter control device (10) performs PWM control on power converters (81A, 81B) supplying power to each of a plurality of winding groups of a multi-winding motor 83 configured from the plurality of winding groups, the power converter control device (10) being provided with a PWM control unit (18) that performs a control to selectively switch between an asynchronous PWM control mode that uses carriers which are not synchronized with voltage commands for the respective winding groups, and either/both of a first synchronous PWM control mode or/and a second synchronous PWM control mode, wherein the first synchronous PWM control mode performs PWM control on the voltage commands for the respective winding groups using carriers that are synchronized with the voltage commands of a specific winding group, and the second synchronous PWM control mode performs PWM control on the voltage commands for the respective winding groups using respective carriers that are synchronized with the respective voltage commands.
