摘要:
An apparatus for charging a battery for a vehicle, includes a PFC circuit including a rectifier for rectifying an AC power to a DC power, and a link capacitor for smoothing the rectified DC power, a bidirectional DC-DC converter including a first switch for converting the DC power of the PFC circuit to an AC power, a transformer for boosting or reducing a voltage of the AC power converted at the first switch, and a second switch for rectifying an AC power from the transformer to a DC power, and a controller configured to control a phase of a PWM signal applied to the second switch such that the link capacitor is charged by an electrical power from the battery, when a voltage of the link capacitor is below a predetermined voltage prior to entering the battery charging mode.
