1. A switched capacitor converter, comprising:
a) a plurality of input switch groups coupled in series between an input terminal and an output terminal, wherein each input switch group comprises two power switches connected in series;
b) a plurality of output switch groups, wherein each output switch group comprises two power switches connected in series between a first terminal of a corresponding output switch group and a second terminal of the corresponding output switch group;
c) a plurality of capacitors, wherein first terminals of the plurality of capacitors are respectively connected with common nodes of every two power switches connected in series in the plurality of input switch groups, and second terminals of the plurality of capacitors are respectively connected with intermediate nodes of each output switch group, wherein the intermediate node is a common node of two power switches in one same output switch group, and
d) a plurality of inductors, wherein the first terminal of each output switch group is connected with a first terminal of a corresponding inductor, and second terminals of the plurality of inductors are connected with the output terminal, and second terminals of the plurality of output switch groups are connected to a reference ground.
