The present invention relates to an electric power conversion system (2; 2a) comprising: an inverter (20); a voltage converter (10; 110) including a high-voltage end connected to a direct-current power source and a low-voltage end connected to the inverter (20); and a controller (8). The controller (8) is configured to control switching elements (3a, 3b) such that a voltage of the low-voltage end becomes lower than a voltage of the high-voltage end in a first state. The controller (8) is configured to control the switching elements (3a, 3b) such that the voltage of the low-voltage end becomes equal to the voltage of the high-voltage end in a second state.
전력 변환기(2; 2a)는, 인버터(20)와, 상기 직류 전원에 접속되어 있는 고전압단과 상기 인버터(20)에 접속되어 있는 저전압단을 포함하는 전압 컨버터(10; 110)와, 컨트롤러(8)를 포함한다. 상기 컨트롤러(8)는, 제 1 상태일 때에는, 상기 저전압단의 전압이 상기 고전압단의 전압보다 낮아지도록 스위칭 소자(3a, 3b)를 제어한다. 상기 컨트롤러(8)는, 제 2 상태일 때에는, 상기 저전압단의 상기 전압이 상기 고전압단의 상기 전압과 동등해지도록 상기 스위칭 소자(3a, 3b)를 제어하도록 구성된다.
