Abstract
A power conversion circuit includes a plurality of solid-state switches coupled between an input terminal and a ground. An output terminal is positioned between two of the plurality of solid-state switches and an inductor is coupled between the output terminal and a load. A capacitor is coupled in parallel with two of the serially connected solid-state switches. A controller controls the plurality of solid-state switches to generate a current in the inductor by repetitively (1) charging the capacitor causing a temporary increase in the current in the inductor, (2) entering a first wait state that configures the plurality of solid-state switches to maintain the capacitor in a charged state, (3) discharging the capacitor causing a temporary increase in the current in the inductor and (4) entering a second wait state that configures the plurality of solid-state switches to maintain the capacitor in a discharged state.
