1. A power conversion circuit comprising:

  • a plurality of serially connected solid-state switches coupled between an input terminal and a ground and including an output terminal;

    an inductor coupled between the output terminal and a load;

    a capacitor coupled in parallel with two of the serially connected solid-state switches; and

    a controller configured to control the plurality of solid-state switches such that a voltage at the load is regulated by repetitively (1) generating a first preflux condition in the inductor and subsequently charging the capacitor causing an increase in current flow in the inductor and (2) generating a second preflux condition in the inductor and subsequently discharging the capacitor causing an increase in current flow in the inductor.
