Abstract
A method includes turning on a first group of switches of a switched capacitor converter in a battery charging system to establish a first conductive path, and configuring a system voltage at a system bus to charge a first flying capacitor to a predetermined voltage level through the first conductive path, wherein the predetermined voltage level is less than the system voltage, and turning on a second group of switches of the switched capacitor converter in the battery charging system to establish a second conductive path to charge a battery, wherein a sum of a voltage across the first flying capacitor and the system voltage is applied to the battery.
