  • Vehicle power supply device
    Patent number: 11021062
    Abstract: A vehicle power supply device includes a first DC/DC converter, a DC/DC controller, a second DC/DC converter, and a vehicle controller. The first DC/DC converter converts a voltage output from a power source, and outputs the converted voltage to a first load. The DC/DC controller controls an operation of the first DC/DC converter. The second DC/DC converter operates by electric power supplied from the power source, and converts the voltage output from the power source and outputs the converted voltage to the DC/DC controller. The vehicle controller controls the DC/DC controller and the first load by supply of the voltage output from the first DC/DC converter and the voltage output from the second DC/DC converter.
