Abstract
An AC-DC power converter can include: a front-stage power circuit; a rear-stage power circuit configured to share one power switch as a main power switch with the front-stage power circuit, where the rear-stage power circuit is coupled to a load, and a first magnetic component of the front-stage power circuit and a second magnetic component of the rear-stage power circuit are not coupled in one conductive loop from a positive terminal of a DC input voltage to a negative terminal of the DC input voltage; and an energy storage capacitor coupled to the front-stage power circuit and the rear-stage power circuit, where a common node of the first and second magnetic components is directly coupled to the power switch.
