The present technology discloses a single stage interleaved totem pole soft switching converter. According to a specific embodiment of the present invention, a backflow is controlled and battery charging and current are integrally controlled based on a PFC circuit of an interleaved totem pole type of a single type, thereby not only reducing the efficiency of a charging apparatus and saving a unit costs thereof, but also removing a harmful electromagnetic wave. A film type capacitor is used instead of a conventional electrolytic capacitor, thereby improving power density and durability. A switching loss can be reduced based on a soft switching operation and the volume of a filter part can be reduced. A magnetization current can be designed to be small by removing a low frequency component of a transformer and a volume thereof can be reduced. Charging with large power is possible according to the number of windings of the transformer.

    본 기술은 단일단 인터리브 토템폴 소프트웨어 스위칭 컨버터가 개시된다. 본 발명의 구체적인 예에 따르면, 단일 방식의 인터리빙 토템폴 타입의 PFC 회로에 의거하여 역류 제어 및 배터리 충전 및 전류를 통합 제어함에 따라 충전 장치의 효율 및 단가 절감뿐만 아니라 유해 전자파를 제거할 수 있고, 기존의 전해 캐패시터 대신 필름형 캐패시터를 이용함에 따라 전력 밀도 및 내구성을 향상시킬 수 있으며, 소프트 스위칭 동작에 의거 스위칭 손실을 감소할 수 있고, 필터부의 부피를 줄일 수 있고, 변압기의 저주파 성분을 제거하여 자화 전류를 작게 설계할 수 있고 부피를 줄일 수 있으며 변압기의 권선 수에 따라 대전력의 충전이 가능하다.
