The present invention relates to a technique for implementing the balancing of a battery pack and a supercapacitor pack using an integrated balancing circuit. To this end, the present invention provides an integrated balancing circuit which has a structure where a battery pack and a supercapacitor pack share the primary wire of a flyback transformer, and each cell of the battery pack and each cell of the supercapacitor pack are multi-wound through the secondary wire of the flyback transformer. Even when the charger of the battery pack and the charger of the supercapacitor pack are used independently, it is possible to transfer electrical energy between the charger of the battery pack and the supercapacitor pack, and to use the electrical energy of an opponent pack as balancing electrical energy.

    본 발명은 하나의 통합된 밸런싱 회로를 이용하여 배터리팩과 슈퍼커패시터 팩의 밸런싱을 구현하는 기술에 관한 것이다. 이를 위해 본 발명은 배터리 팩과 슈퍼커패시터 팩이 플라이백 트랜스포머의 일차 권선을 공유하고, 배터리 팩의 각 셀과 슈퍼커패시터 팩의 각 셀들이 플라이백 트랜스포머의 이차 권선들을 통해 멀티 와인딩되는 구조를 갖는 통합된 밸런싱 회로를 구현함으로써, 배터리 팩의 충전기와 슈퍼커패시터 팩의 충전기가 각각 독립적으로 사용중인 경우에도 배터리 팩의 충전기와 슈퍼커패시터 팩 간의 전기 에너지 전달이 가능하고 상대 팩의 전기 에너지를 밸런싱 전기 에너지로 사용하는 것이 가능하도록 하였다.
