The present disclosure relates to a new bidirectional low voltage DC-DC converter (LDC), that is, a DC-DC converter capable of satisfying a safety level required for an eco-friendly vehicle and an autonomous vehicle and improving power conversion performance, and a method and an apparatus for controlling the same. The LDC proposed in the present disclosure is a new concept bidirectional LDC in which a plurality of converters having the same power circuit topology are subjected to a parallel interleaving operation so as to enable both a buck operation and a boost operation, satisfy a high safety level, and improve power conversion performance. To this end, a plurality of bidirectional active-clamp flyback converters (for example, two or more bidirectional active-clamp flyback converters) are connected in parallel and are interleaved and controlled by a controller (for example, a microcomputer).
