Abstract
A switched-capacitor converter includes a rectifier at the output, a plurality of legs coupled between the input and the rectifier, and a controller. Each leg of the switched-capacitor converter includes a capacitor, and a switch device is connected to each leg. A first group of the legs is coupled to a first branch of the rectifier, and a second group of the legs is coupled to a second branch of the rectifier. The controller alternates switching of the first and second groups of legs after startup, to transfer energy from the input to the output during a first part of each switching cycle via the first group of legs and to ground during a second part of each switching cycle via the second group of legs. The controller or a current limited source provides for pre-charging of at least one of the capacitors during startup.
