1. An electrified vehicle comprising:
a battery;
a motor including a plurality of windings;
a power factor correction circuit including AC terminals and DC terminals, the power factor correction circuit including a plurality of legs respectively corresponding to the AC terminals while being connected between the DC terminals; and
a DC/DC converter including a first switching circuit including first, second, and third primary legs connected between first and second terminals of the battery, a second switching circuit including at least one secondary leg connected between the DC terminals, and a transformer connected between the first switching circuit and the second switching circuit,
wherein, when a battery discharging mode is performed, the DC/DC converter switches the first primary leg and the at least one secondary leg, and outputs a voltage of the battery to the DC terminals via the transformer,
wherein, when the motor is to be driven, the DC/DC converter switches the second and third primary legs electrically disconnected from the transformer, and outputs the voltage of the battery to the motor,
wherein the first switching circuit is connected between the battery and the transformer and the second switching circuit is connected between the DC terminals, and
wherein the DC/DC converter further includes:
a first switch configured to electrically connect the second primary leg to one of the motor and the transformer in accordance with whether the motor is to be driven; and
a second switch configured to electrically connect the third primary leg to one of the motor and the transformer in accordance with whether the motor is to be driven, and
wherein a first end of the first switch is connected to the second primary leg of the first switching circuit, a second end of the first switch is selectively connectable to the one of the transformer or the motor, a first end of the second switch is connected to the third primary leg of the first switching circuit, and a second end of the second switch is selectively connectable to the one of the transformer or motor.
