Abstract

A drive system includes a first inverter electrically connected to a first AC rotating electrical machine, a second inverter electrically connected to first end sides of phase coils constituting a second AC rotating electrical machine, a boost converter, and a third inverter electrically connected to a second end sides of phase coils and drives the second AC rotating electrical machine by transmitting electrical power between the third inverter and a second DC power source different from a first DC power source. The drive system is configured such that the second DC power source and the first AC rotating electrical machine are connected via a single connecting route. The drive system includes a processor that changes a control state of at least one of the first to third inverters and the boost converter based on a state of at least one of the first to third inverters, the boost converter, and the first and second DC power sources.
