The present invention relates to a power supply apparatus using a flyback converter circuit capable of previously diagnosing the abnormality of various elements included in a circuit of an electric vehicle before a current is supplied from a main battery by firstly supplying the current to the circuit of the electric vehicle after varying the current supplied from a separate auxiliary battery using the flyback converter circuit by being provided between the main battery and the circuit of the electric vehicle and blocking the power supply to the main battery when the abnormality is detected. The power supply apparatus using a flyback converter circuit includes a power source unit for receiving power, an input circuit including a first winding and a signal switch, an output circuit including a second winding, and a control unit which changes the signal transmission path of the first winding.
본 발명은 전기 자동차의 메인 배터리와 회로 사이에 제공되어 별도의 보조 배터리로부터 공급되는 전류를 플라이백 컨버터 회로를 이용하여 가변한 후 이를 전기 자동차의 회로에 우선적으로 인가함으로써, 메인 배터리로부터 전류가 공급되기 전에 전기 자동차의 회로 상에 포함된 다양한 소자들의 이상 유무를 미리 진단하고, 이상 발견 시 메인 배터리의 전원 공급이 차단되도록 하는 플라이백 컨버터 회로를 이용한 전원 공급 장치에 관한 것이다.
