Abstract
A switching circuit for extracting power from an electric power source includes (1) an input port for electrically coupling to the electric power source, (2) an output port for electrically coupling to a load, (3) a first switching device configured to switch between its conductive state and its non-conductive state to transfer power from the input port to the output port, (4) an intermediate switching node that transitions between at least two different voltage levels at least in part due to the first switching device switching between its conductive state and its non-conductive state, and (5) a controller for controlling the first switching device to maximize an average value of a voltage at the intermediate switching node.
