Original Abstract Submitted
An electrified vehicle includes a motor including windings, a power factor correction circuit including AC and DC terminals and including legs corresponding to respective AC terminals and connected between the DC terminals, and a DC/DC converter including a first switching circuit including first, second, and third primary legs connected between terminals of a battery, a second switching circuit including at least one secondary leg connected between the DC terminals, and a transformer connected between the first and second switching circuits. In a battery discharging mode, the DC/DC converter switches the first primary leg and the at least one secondary leg, outputting a voltage of the battery to the DC terminals via the transformer. When the motor may be driven, the DC/DC converter switches the second and third primary legs electrically disconnected from the transformer, outputting the voltage of the battery to the motor.
