Abstract

Provide is a power supply redundant system in which power supply systems of different voltages coexist, which allows electric power to be supplied to a load even if a ground fault or short circuit occurs therein. The system includes a DCDC converter, a first side of the DCDC convertor being connected to a first battery having a first voltage, a first switch provided between a second battery having a second voltage different from the first voltage and a second side of the DCDC converter, a load operating with the second voltage, separately connected to the second battery and the second side of the DCDC converter, and a controller monitoring a voltage of the second battery by turning on the first switch, and when the voltage of the second battery becomes equal to or lower than a first reference value, switching off the first switch and allowing the DCDC converter to output the second voltage from the second side.
