1. A power conversion system comprising:
one or more switched capacitor converters connected between an input dc source and a plurality of interleaved multilevel voltage rails, wherein in a first part of one switching cycle of one switched capacitor converter of the one or more switched capacitor converters, the input dc source is configured to charge at least one flying capacitor through a first group of switches of the one switched capacitor converter, and in a second part of the switching cycle of the one switched capacitor converter, the at least one flying capacitor is configured to provide power for at least one of the plurality of interleaved multilevel voltage rails through a second group of switches of the one switched capacitor converter;
one or more inductor links connected to the plurality of interleaved multilevel voltage rails; and
one or more output cells, wherein each output cell is connected to an output load and all of the plurality of interleaved multilevel voltage rails through a corresponding inductor link.
