The charging device according to the present invention comprises: a power factor correction (PFC) circuit including first to third inductors and first to third switch legs connected to each of the first to third inductors; a relay network which controls the connection between the first to third inductors and first to third input terminals according to the phase of the power system connected to the first to third input terminals; and a capacitor including one end connected to the neutral point for the first to third input terminals and the other end connected to the ground. The relay network includes a first relay connected between the neutral point and the third inductor, and one end of the capacitor may be located closer to the neutral point than the first relay. Accordingly, the present invention enables charging operation with high charging efficiency.

    본 발명에 따른 충전 장치는, 제1 내지 제3 인덕터, 및 상기 제1 내지 제3 인덕터 각각에 연결된 제1 내지 제3 스위치 레그를 포함하는 PFC(Power Factor Correction) 회로, 상기 제1 내지 제3 인덕터와 제1 내지 제3 입력단 간의 연결을, 상기 제1 내지 제3 입력단에 연결된 전력 계통의 상에 따라 제어하는 릴레이 네트워크, 및 상기 제1 내지 제3 입력단에 대한 중성점에 연결되어 있는 일단 및 그라운드에 연결되어 있는 타단을 포함하는 커패시터를 포함한다. 상기 릴레이 네트워크는, 상기 중성점과 상기 제3 인덕터 사이에 연결되어 있는 제1 릴레이를 포함하고, 상기 커패시터의 일단은 상기 제1 릴레이보다 상기 중성점에 더 가까이에 위치할 수 있다.
