1. A half-bridge switching circuit system comprising:
a first plurality of switches arranged between a first rail voltage and an output on which an output voltage is provided;
a second plurality of switches arranged between a second rail voltage and the output, the first and second pluralities of switches being controlled via a plurality of switching signals;
a plurality of flying capacitors arranged to interconnect the first and second pluralities of switches; and
a plurality of snubber circuits that are each arranged in parallel with a respective one of the plurality of flying capacitors, the first plurality of switches, and the second plurality of switches.
