PROBLEM TO BE SOLVED: To provide a power conversion system which can suppress decrease in conversion efficiency at the time of power output of a DC/DC converter.SOLUTION: A power conversion system includes: a DC/DC converter 10 which is connected to an electric load 8 and a sub-battery 7 for supplying electric power to the electric load 8, converts electric voltage of supply power, and outputs electric power to the electric load 8 and the sub-battery 7; a voltage sensor 101 which detects output voltage of the sub-battery 7; a current sensor 102 which detects output current Iout of the DC/DC converter 10; and a control section 11 which starts output of the DC/DC converter 10 when the output voltage is lower than voltage V1, and then stops output of the DC/DC converter 10 when the output current Iout is lower than reference current. The control section 11, during the output, outputs electric power while restricting the output current Iout so that the output current Iout may not exceed the reference current. |
