A charger is provided to convert AC power to generate DC power capable of charging an energy storage device. The charger includes a switching circuit unit that applies or blocks AC power input from the outside and a power factor correction circuit unit that converts the AC power applied from the switching circuit unit into DC power. A DC-DC converter then converts a voltage level of the DC power converted by the power factor correction circuit and supplies the converted voltage level of the DC power to an energy storage device. A capacitor configured is shunt-connected between the power factor correction circuit unit and the DC-DC converter. A controller operates the switching circuit unit and the power factor correction circuit unit to charge the capacitor with a predetermined voltage at an initial charging operation of the energy storage device.
