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.
