Abstract
A control circuit having extended hold-up time is coupled to a bus path of a conversion circuit. The control circuit includes a bypass circuit, an energy storage capacitor, and an auxiliary power circuit. The auxiliary power circuit supplies an energy storage voltage to the energy storage capacitor according to a working voltage provided by the conversion circuit. When a bus voltage of the bus path is less than or equal to the energy storage voltage, the energy storage voltage is supplied to the bus path through the bypass circuit so that the bus voltage is greater than or equal to a predetermined voltage within a hold-up time.
