  • Patent number: 8295024
    Abstract: A surge energy transfer circuit comprises a surge protection device, gas tube, inductor and high voltage capacitor for significantly reducing surge energy entering a power facility, lowering a remnant surge voltage to convert the surge energy in a voltage form. The converted voltage is superimposed to an operating power to slightly cause a rise of a peak value of the operating voltage. After the surge energy is converted in tens of mS, the operating power returns to a normal voltage value. Accordingly, the lifetime of the surge protection device can be extended and the surge immunity of the power facility can be improved to normal under surge interference situations.
