    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.

    摘要： A heat dissipation structure of transformer includes a bobbin formed with a hollow shape and wound with a primary coil and a secondary coil. A core surrounds an inside and an outside of the bobbin by combining a pair of upper cores with a pair of lower cores. A heat dissipating plate is disposed between the pair of upper cores and the pair of lower cores. According to an exemplary embodiment of the present disclosure, heat generated inside of the core can be effectively exhausted outside by a heat dissipating plate disposed in the center of the core.
