Abstract
A control circuit of a power conversion circuit includes an energy storing circuit coupled between an AC/DC rectifier circuit and a DC/DC conversion circuit. When a first condition 'the absolute peak value of the input voltage of the AC/DC rectifying circuit is smaller than a reference voltage' is satisfied, discharge current is provided for lowering the voltage on the first output end of the AC/DC rectifying circuit. When the first condition and a second condition “the discharge current is smaller than reference current” are both satisfied, a switch of the energy storing circuit is turned on. When the first condition and the second are not both satisfied, the switch of the energy storing circuit is turned off.
