摘要： A power supply device includes a battery 1, an output switch 2 connecting the battery 1 to a load 20, and a control circuit 3 controlling the output switch 2. The output switch 2 is a semiconductor switching element 11 having controllable ON resistance. In the power supply device, the ON resistance of the semiconductor switching element 11 is controlled by the control circuit 3 so that the ON resistance in a precharge state is set larger than the ON resistance in an electrically-conducted state. The parallel capacitor 23 of the load 20 is precharged in the precharge state. After the parallel capacitor 23 of the load 20 is precharged, the load 20 is supplied with power from the battery 1 with the semiconductor switching element 11 being brought into the electrically-conducted state in which the ON resistance of the semiconductor switching element 11 is smaller than the precharge state.
