본 발명은 단상-3상 겸용식 변환회로를 공개하는 데, 그는 EMC모듈, PFC모듈, 스위치K1 및 제어모듈을 포함하되, 상기 EMC모듈은 전력망의 A, B, C, N라인과 상기 PFC모듈 사이에 연결되고 상기 EMC모듈이 인출하는 A1, B1, C1 3개 라인은 상기 PFC모듈과 서로 연결되며, A1, B1, C1 3개 라인은 각각 커패시터 CX1, CX2와 CX3을 통해 설치된 가상 중점까지 연결되고, 상기 가상 중점은 상기 스위치K1을 통해 상기 PFC모듈의 모선 중점과 서로 연결되며, 상기 제어모듈은 전력망 입력신호를 검측하고 전력망 입력신호의 유형에 근거해 상기 스위치K1의 상태를 제어하는 데 사용된다. 본 발명의 기술방안을 이용하면 3상변환모드 공통모드 잡음을 줄일 수 있을 뿐만 아니라, 3상변환모드에 모선 전압 조정 범위가 비교적 큰 제어방식을 이용할 수 있도록 보장할 수 있으며; 단상변환모드로 전환할 때에도 직류측의 공통모드 잡음이 입력형 EMC에 미치는 영향을 줄일 수 있다.

    A single-phase and three-phase compatible conversion circuit includes an EMC module, a PFC module, a switch K1 and a control module. The EMC module is connected between lines A, B, C and N of a power grid and the PFC module. Three lines A1, B1 and C1 are led out from the EMC module and are connected with the PFC module, and are respectively connected to a set virtual midpoint through capacitors CX1, CX2, and CX3. The virtual midpoint is connected to a bus midpoint of the PFC module through the switch K1. The control module is used for detecting a power grid input signal and controlling the state of the switch K1 according to the type of the power grid input signal. The common-mode noise of the three-phase conversion mode can be reduced, and the three-phase conversion mode can be controlled within a larger bus voltage regulation range.
