  • Patent number: 8953351
    Abstract: A power conversion apparatus is provided. The power conversion apparatus includes an AC to DC adapter, an input port, a power conversion control unit, and a restart circuit. The AC to DC adapter converts an AC input voltage into a DC output voltage according to an external signal of an electronic apparatus and provides the DC output voltage to the electronic apparatus. The input port receives the AC input voltage through an AC input terminal. If the power conversion apparatus does not output the DC output voltage to the electronic apparatus, the power conversion control unit turns off the power conversion apparatus. If the restart circuit detects that an insertion action occurs on the input port, the restart circuit transmits a trigger signal to turn on the power conversion control unit in an off mode.
