Abstract
A power converter is connected between a power supply line and a ground line, and the power supply line is connected to a battery. The power converter supplies converted power to a load by converting direct current power of the battery. A control circuit controls the power converter by a voltage applied from the battery. A reverse-connection protective relay is connected to the ground line, and interrupts a current flowing from the ground line to the power supply line via the power converter in a case where the battery is connected in a reverse direction. A voltage required for turning on the reverse-connection protective relay is applied to a gate of the reverse-connection protective relay in a case where the battery is connected in a forward direction, and is not applied to the gate of the reverse-connection protective relay in a case where the battery is connected in the reverse direction.
