摘要： A power supply apparatus includes a first output power circuit, a first output protection circuit, a first output capacitor, a first pre-charging circuit and a first power supply control circuit. The first output power circuit is used for generating a first internal output voltage. The first output protection circuit is connected to a power output terminal of the first output power circuit for limiting the current direction. The first pre-charging circuit is interconnected between a power input terminal and a power output terminal of the first output protection circuit for providing a first pre-charging path. When the first power-on signal is switched from a disabled status to an enabled status, a first pulse width modulation signal having a higher or the maximum duty cycle is transmitted from the first power supply control circuit to the control terminal of the first switching circuit, thereby enabling the first output power circuit.
