Abstract
A period determination circuit for determining conduction period for energy-recycling circuit includes an indication circuit, coupled to an inductor of the energy-recycling circuit to receive an inductor voltage, configured to generate an indication signal according to the inductor voltage, wherein the indication signal reflects a status corresponding to a first conduction period of the energy-recycling circuit; and a control signal generator, coupled to a switch of the energy-recycling circuit, configured to generate a control signal with a second conduction period for the switch according to the indication signal. The energy-recycling circuit is coupled to a first capacitive component and a second capacitive component. The energy-recycling circuit comprises the inductor and the switch coupled between the first capacitive component and the second capacitive component. The control signal generator determines the second conduction period according to the first conduction period and the indication signal.
