A power supply device includes an energy storage device that supplies a first voltage, and a converter that converts a second voltage into the first voltage. The power supply device includes a first switching element coupled to the converter and at least one load of the vehicle, and a second switching element coupled to the first switching element and the at least one load. The power supply device includes a controller that determines a failure condition for the converter or the energy storage device, and controls, in response to determining the failure condition, the first switching element and the second switching element such that i) the converter is disconnected from or connected to the at least one load, and ii) the energy storage device is disconnected from or connected to the at least one load.
