Original Abstract Submitted
a battery charging system can include a stacked half bridge rectifier (“shbr”) having an upper half bridge (“uhb”) and a lower half bridge (“lhb”); a blocking capacitor and a winding coupled between a midpoint of the uhb and a midpoint of the lhb; a battery coupled across the shbr; and control circuitry that can selectively operate the shbr as a switched capacitor converter (“scc”) using the blocking capacitor as a flying capacitor by alternating between: a first switching state in which lower switches of the uhb and lhb are closed while upper switches of the uhb and lhb are opened; and a second switching state in which upper switches of the uhb and lhb are closed. the battery can further include first and second series-connected batteries having a midpoint coupled to a midpoint of the shbr, and the scc can operate as a balancer to equalize charge between the batteries.
