Original Abstract Submitted
a power conversion system can include at least one stacked half bridge converter that further includes a first half bridge further comprising two switching devices in a half bridge configuration and a first capacitor coupled thereacross and a second half bridge further comprising two switching devices in a half bridge configuration and a second capacitor coupled thereacross. the at least one stacked half bridge converter can be disposed between an input of the power conversion system and an output of the power conversion system. the power conversion system can further include a transformer coupled to the at least one stacked half bridge converter by a blocking capacitor and control circuitry that operates the switching devices of the at least one stacked half bridge converter as a switched capacitor converter using the blocking capacitor as a flying capacitor to equalize charge between the first and second capacitors.
