Abstract: An activation circuit with surge suppression is coupled to an output capacitor of a conversion apparatus. The activation circuit includes a detection circuit, a control circuit, and a surge suppression switch. The detection circuit provides an input signal to the control circuit according to an AC voltage received by an input end of the conversion apparatus, and determines whether the AC voltage is in a zero-crossing range according to the input signal. When the AC voltage in the zero-crossing range, the control circuit controls the surge suppression switch to connect a current path between the output capacitor and a ground end so as to active the conversion apparatus.
