摘要
The present invention reduces the number of magnetic sensors. This drive device for a three-phase rotating electric machine is mounted on a vehicle and provided with: a plurality of switching elements for energizing the three-phase windings of the three-phase rotating machine by performing switching operations; and a control unit for controlling the switching operations of the plurality of switching elements. The control unit performs a first control for controlling the switching operations using four energization patterns indicating the ON-state or OFF-state of the plurality of switching elements, thereby driving the three-phase rotating electric machine.
