A hybrid vehicle includes a battery, a boosting converter, first and second inverters, a first inverter 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. The control unit increases one or both of carrier frequencies Fc1, Fc2 of the first and second inverters as a real boost voltage VHr increases during a suspended state of the boosting converter. The control unit decreases one or both of the carrier frequencies of the first and second inverters as real boost voltage VHr decreases during a suspended state of the boosting converter. System efficiency of an electric vehicle can be improved effectively by increasing the suspension time of the boosting converter, while securing drivability of the vehicle.
