ABSTRACT:
A drive device having at least one electric motor that inputs and outputs motive power includes: a plurality of capacitors; a plurality of relays for capacitors that connects and disconnects the motor and the capacitors; and a relay control device that controls the relays for capacitors. The relay control device controls the plurality of relays for capacitors so that during a system start-up, a part of the plurality of relays for capacitors are connected, that is, a partially-on-state is established, after a first predetermined condition is satisfied during the partially-on-state, the part of relays for capacitors are disconnected and a remaining part of the plurality of relays for capacitors are connected, and after a second predetermined condition is satisfied during the remainder-on-state, all the plurality of relays for capacitors are connected.
