A power supply system includes a first circuit (100), a second circuit (200) and a voltage controller (10). The first circuit (100) includes a first power supply line (102) connected to each of first loads (120, 121, 122, 123, 124, 125, 126, 127), a power supply source (103), and a first battery (101). The second circuit (200) includes a second power supply line (202) connected to second loads (211, 212, 213, 214, 215, 216, 217, 218, 219) and a second battery (201) connected to the second power supply line (202). The voltage controller (10) includes a DC-DC converter (17) connected between the first power supply line (102) and the second power supply line (202). The second loads (211, 212, 213, 214, 215, 216, 217, 218, 219) can perform a function which substitutes for at least part of a function which the first loads (120, 121, 122, 123, 124, 125, 126, 127) perform. The voltage controller (10) includes a converter control unit (13) configured to control the DC-DC converter (17) such that an output voltage higher than or equal to a voltage of the second battery (201) is output to the second power supply line (202). The power supply system can back up the function of the first loads by the function of the second loads. 전원 장치는, 제1 회로(100)와 제2 회로(200)와 전압 제어 장치(10)를 구비한다. 제1 회로(100)는 제1 부하(120, 121, 122, 123, 124, 125, 126, 127), 전력 공급원(103), 제1 배터리(101)의 각각에 접속된 제1 전원 라인(102)을 포함한다. 제2 회로(200)는 제2 부하(211, 212, 213, 214, 215, 216, 217, 218, 219)에 접속된 제2 전원 라인(202)과, 제2 전원 라인(202)에 접속된 제2 배터리(201)를 포함한다. 상기 전압 제어 장치(10)는 제1 전원 라인(102)과 제2 전원 라인(202) 사이에 접속된 직류-직류 변환기(17)를 포함한다. 상기 제2 부하(211, 212, 213, 214, 215, 216, 217, 218, 219)는 상기 제1 부하(120, 121, 122, 123, 124, 125, 126, 127)가 실행하는 기능 중 적어도 일부를 대체하는 기능을 실행 가능하고, 상기 전압 제어 장치(10)는 상기 제2 배터리(201)의 전압 이상의 출력 전압이 제2 전원 라인(202)에 출력되도록 상기 직류-직류 변환기(17)를 제어하도록 구성되어 있는 컨버터 제어부(13)를 갖는다.
