POWER SUPPLY MODULE

A characteristic configuration of a power supply module according to the present disclosure includes a power supply module mounted on a vehicle, the power supply module including an AC-DC conversion unit that converts one of an AC voltage and a DC voltage into the other and outputs the other, and a voltage conversion unit that converts a first voltage value of an input DC voltage into a DC voltage having a second voltage value, the voltage conversion unit includes a first conversion unit connected to the AC-DC conversion unit and a second conversion unit connected to the first conversion unit via a transformer, and the power supply module including a first board on which the AC-DC conversion unit and the first conversion unit are provided, and a second board on which the second conversion unit is provided and that is different from the first board.
