Disclosed are an electric vehicle capable of improving the charging efficiency of a charging apparatus by reducing the switching loss that may occur in the charging apparatus of an electric vehicle and a charging apparatus thereof. To this end, a power factor correction apparatus of an on board charger includes a first boost circuit receiving AC power through a first inductor to charge a load, a second boost circuit receiving the AC power through a second inductor to charge the load, and a third inductor provided between a leg of the first boost circuit and a leg of the second boost circuit so that parasitic capacitors of the first boost circuit and the second boost circuit are discharged.

Electric vehicle and charging apparatus thereof

A discrete capacitance switching circuit includes a DC decoupling capacitor connected between a power node that receives an AC signal and a first node, a diode connected between the first node and a second node, a unit capacitor connected between the second node and a reference node that receives a ground voltage, and a bias circuit. The bias circuit is configured to apply a first DC voltage to the first node and apply a second DC voltage to the second node. The applied first and second DC voltages control a switching operation of the diode.
