  • Publication number: 20230114632
    Abstract: A switched-mode power regulator circuit has four solid-state switches connected in series and a capacitor and an inductor that regulate power delivered to a load. The solid-state switches are operated such that a voltage at the load is regulated by repetitively (1) prefluxing the inductor then charging the capacitor causing an increased current to flow in the inductor and (2) prefluxing the inductor then discharging the capacitor causing increased current to flow in the inductor. The inductor prefluxing steps enable the circuit to provide increased output voltage and/or increased output current.

    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.
