Abstract: A power supply unit supplies power to a load, and the power supply unit includes a power factor corrector, a DC conversion module, and an isolated conversion module. The power factor corrector is plugged into a first main circuit board and converts an AC power into a DC power. The DC conversion module is plugged into the first main circuit board and converts the DC power into a main power. The isolated conversion module includes a bus capacitor, the bus capacitor is coupled to the DC conversion module through a first power copper bar, and coupled to the power factor corrector through a second power copper bar. The first power copper bar and the second power copper bar are arranged on a side opposite to the first main circuit board, and are arranged in parallel with the first main circuit board.

Abstract: A power supply apparatus includes a bulk capacitor, a voltage dropper unit and a pre-charging capacitor. The voltage dropper unit is electrically connected to the bulk capacitor. The pre-charging capacitor is electrically connected to the voltage dropper unit. When the power supply apparatus receives an input direct current voltage, a voltage of the bulk capacitor is provided with a first voltage, and the pre-charging capacitor is charged so that the pre-charging capacitor is provided with a second voltage, and the second voltage is greater than the first voltage. When the voltage of the bulk capacitor is less than a predetermined voltage, the second voltage of the pre-charging capacitor is converted voltage by the voltage dropper unit to provide for extending a hold up time of the power supply apparatus.

Abstract: A power supply includes a conversion circuit, an auxiliary power circuit, and an output control circuit. The conversion circuit converts a DC power into a first output power, and the auxiliary power circuit converts the DC power into a first auxiliary power. The output control circuit is used to selectively connect a first output terminal and a second output terminal so that when the output control circuit disconnects the first output terminal and the second output terminal, the first output power supplies power to a critical load through the first output terminal, and when the output control circuit connects the first output terminal and the second output terminal, the first output power supplies power to the critical load and a non-critical load through the first output terminal and the second output terminal respectively.
