The present disclosure relates to a multi-functional multi-ratio OBC/LDC integrated circuit that is capable of bidirectional operation over a broad voltage rage with a high power density and without additional control in a battery charging system for an electric vehicle. As the turns ratio can be used selectively, the G2V and V2G functions can be performed bidirectionally over a broad voltage range without additional control, and the LDC function can be operated by using only a small number of switches, so that the efficiency of the charging control can be increased.
