Claim Text:
1. An electric vehicle, comprising: a battery; a boosting converter connected to the battery; a first inverter connected to the boosting converter; a second inverter connected to the boosting converter and the first inverter; a first motor generator connected to the first inverter; a second motor generator connected to the second inverter; and a control unit configured to start and suspend the boosting converter, wherein during a suspended state of the boosting converter, the control unit increases a carrier frequency of one of the first and second inverters having a larger increasable amount of the inverter loss, which is generated by the increase of the carrier frequency, as a real boost voltage increases, and decreases a carrier frequency of one of the first and second inverters having a larger decreasable amount of the inverter loss, which is generated by the decrease of the carrier frequency as the real boost voltage decreases, wherein the real boost voltage is an output voltage of the boosting converter.
