According to the present technology, disclosed is a charger for both a three-phase and a single-phase. According to a specific example of the present invention, a battery charger of a single-phase and three-phase single-terminal structure is realized without an electrolytic capacitor that lowers reliability and charging efficiency to be compatible with single-phase and three-phase external power sources, charging efficiency and performance of a wide input/output voltage range can be increased with a reduced number of switching elements and a switching operation of the switching elements, reliability and a lifespan can be increased, and at least two of an inductor for ripple removal of the battery charger, a primary side and a secondary side of a transformer, and an inductor for noise removal are integrated into one core to realize a lightweight charger.

    본 기술은 삼상 및 단상 겸용의 충전기가 개시된다. 본 발명의 구체적인 예에 따르면, 신뢰성 및 충전 효율을 저하시키는 전해 캐패시터 없이 단상 및 삼상 겸용의 단일단 구조의 배터리 충전기를 구현함에 따라 단상 및 삼상의 외부 전원에 대해 호환 가능하고, 감소된 스위칭 소자의 수와 스위칭 소자의 소프트 스위칭 동작으로 충전 효율 및 넓은 입출력 전압 범위의 성능을 향상시킬 수 있으며, 신뢰성 및 수명을 향상시킬 수 있고, 배터리 충전기의 리플 제거용 인덕터와 변압기의 1차측 및 2차측과 노이즈 제거용 인덕터 중 적어도 둘을 하나로 코어로 통합함에 따라 경량의 충전기를 구현할 수 있다.
