摘要:
A drive apparatus is provided for driving a rotating electric machine having first and second multi-phase coils. The drive apparatus includes first and second inverters, first and second shift switches, and first and second energization controllers. The first energization controller is configured to turn on and off, for each of phase windings of the first and second multi-phase coils, one corresponding pair of upper-arm and lower-arm switches of the first and second inverters while keeping the first and second shift switches in an OFF state. The second energization controller is configured to turn on and off, for each corresponding pair of the phase windings of the first and second multi-phase coils, one corresponding upper-arm switch of the first inverter and one corresponding lower-arm switch of the second inverter respectively for first energization periods and second energization periods that are alternately set while keeping the shift switches in an ON state.
