Abstract
A single-stage battery charger system includes a switched capacitor converter coupled between an input power source and a load, an inductor coupled between a midpoint of the switched capacitor converter and the load, and an isolation switch coupled between the midpoint and the load, wherein the isolation switch is configured such that the single-stage battery charger system functions as a multilevel switching charger when the isolation switch is turned off, and the single-stage battery charger system functions as a switched capacitor charger when the isolation switch is turned on.
