Abstract

A drive device that includes an alternating-current rotary electric machine in which currents of a plurality of phases flow; an inverter that includes switching element units for respective phases corresponding to the respective phases, and that is connected between a direct-current power supply and the alternating-current rotary electric machine and performs conversion between a direct current and an alternating current; and shunt resistors that detect currents flowing in the respective switching element units for the corresponding phases between the direct-current power supply and the switching element units for the respective phases.
