Original Abstract Submitted
a drive system includes: a first inverter that outputs first alternating current by switching first direct current with a switching element (first switching element), to an electric motor generating power for propelling a vehicle; a second inverter that supplies, to the electric motor, second alternating current having the same frequency as the first alternating current by switching direct current with a switching element (second switching element); and a control part that performs pwm control on the first inverter and the second inverter such that an on-time of the first switching element in one cycle of the first alternating current becomes longer than an on-time of the second switching element when the direct current is smaller than the direct current.
