Abstract
A power conversion circuit includes an inductive switching power converter and a capacitive switching power converter. The inductive switching power converter switches an inductor to converter a DC power to a first power. The capacitive switching power converter switches a conversion capacitor to convert the first power to a charging power for charging a battery. The inductive switching power converter and the capacitive switching power converter flexibly operate in and dynamically switch between a regulation mode, a bypass mode or a combination thereof according to a parameter of the DC power.
