Claim 17:
18. A method comprising:
providing a switched capacitor converter comprising:
a first leg comprising a plurality of first leg switches and a second leg comprising a plurality of second leg switches;
a first flying capacitor connected to the first leg, a second flying capacitor connected to the second leg, and a third flying capacitor connected between the first leg and the second leg; and
a first upper switch and a second upper switch connected to two terminals of the third flying capacitor respectively;

in a first half cycle, configuring the plurality of first leg switches, the plurality of second leg switches, the first upper switch and the second upper switch such that the third flying capacitor, the first flying capacitor and an output capacitor are connected in series, and the second flying capacitor and the output capacitor are connected in parallel; and
in a second half cycle, configuring the plurality of first leg switches, the plurality of second leg switches, the first upper switch and the second upper switch such that the first flying capacitor and the output capacitor are connected in parallel, and the third flying capacitor, the second flying capacitor and the output capacitor are connected in series.
