Abstract
A rotating electric machine apparatus includes a rotating electric machine and a full-bridge inverter. The full-bridge inverter includes first high-side switches, first low-side switches, second high-side switches, and second low-side switches. The rotating electric machine apparatus includes: first and second neutral point switches; a full-wave driving unit that performs a full-wave driving process in which switching control of the switches is performed in a state in which the first and second neutral point switches are turned off; a half-wave driving unit that performs a half-wave driving process in which switching control of the first high-side switches and the second low-side switches is performed in a state in which the first and second neutral point switches are turned on, and the first low-side switches and the second high-side switches are turned off; and an executing unit that selects and performs either of the full-wave driving process and the half-wave driving process.
