The present invention discloses an input filter circuit device for single phase/three phase of a charger for an electric vehicle. The input filter circuit device comprises: a CM filter unit in which an inductor is mediated to each of the R phase line, the S phase line, the T phase line, and the N phase line; and a phase inversion switching unit switching input power to be outputted through an inductor mediated to the S phase line through an inductor mediated to the R phase line of the CM filter unit and switching the input power to be outputted through an inductor mediated to the N phase line through an inductor mediated to the T phase line of the CM filter unit when a phase inversion signal is a single phase inversion signal.
본 발명은 전기 자동차용 충전기의 단상/삼상 겸용 입력필터 회로장치가 개시된다. 본 발명의 전기 자동차용 충전기의 단상/삼상 겸용 입력필터 회로장치는, R상 라인, S상 라인, T상 라인 및 N상 라인 각각에 인덕터가 매개되는 CM 필터부; 및 상 전환 신호가 단상 전환 신호일 때, 입력 전원이 CM 필터부의 R상 라인에 매개된 인덕터를 경유하여 S상 라인에 매개된 인덕터를 통해 출력되도록 전환하고, T상 라인에 매개된 인덕터를 경유하여 N상 라인에 매개된 인덕터를 통해 출력되도록 전환하는 상 전환 스위칭부를 포함하는 것을 특징으로 한다.
