Claim 3:
4. The power converter of claim 1, wherein the first pair of switching device comprises a first switching device and a second switching device, the second pair of switching device comprises a third switching device and a fourth switching device, the first switching device, the second switching device, the third switching device, and the fourth switching device are controlled by a first switch control signal, a second switch control signal, a third switch control signal, and a fourth switch control signal, respectively, the power converter further comprising a first input capacitor coupled across the first and second switching devices and a second input capacitor coupled across the third and fourth switching devices; wherein, when the first input capacitor has a voltage greater than that of the second input capacitor, the control circuit delays transitions in the first and second switch control signals and brings forward in time transitions of the third and fourth switch control signals by the same amount, when the first input capacitor has a voltage less than that of the second input capacitor, the control circuit brings forward in time transitions in the first and second switch control signals and delays transitions of the third and fourth switch control signals.
