Abstract
A system for supplying a load comprising: an input inductor configured to receive an input voltage, a selection module connected to the inductor via a switching node, and a multi-level half-bridge stage comprising a plurality of half-bridge stages, each half-bridge stage comprising a pair of switches connected between a switching node; a power combining stage coupled to each half-bridge stage using parallel bus voltage lines output from the multi-level half-bridge stage, the power combining stage configured to output a voltage to the load; and a controller configured, based on the input voltage, to selectively control a half-bridge stage to operate in a half-bridge mode to provide a stepped-up voltage on a bus voltage line, wherein the controller is further configured to control the power combining stage to provide a voltage between the bus voltage lines and the sum of these voltages is higher than a peak of the input voltage.
