    • A control circuit is applied to a power converter which controls the input current of the power converter. The power converter outputs an amount of output electric charge which is predetermined in each line cycle. The control circuit comprises: an input current control circuit; an output electric charge detection circuit; and a gating logic circuit. The input current control circuit controls the input current of the power converter by generating PWM signals. When the amount of the output electric charge outputted by the power converter in a single line cycle reaches a predetermined amount, the output electric charge detection circuit generates a gating logic signal. A gating logic circuit controls the switch of the power converter according to the gating logic signal and the PWM signals. The power converter outputs the amount of output electric charge which is predetermined in each line cycle.
