1. A method for switching a resonant switched-capacitor converter (RSCC), comprising:
operating switches of the RSCC in a repeated asymmetric sequence of switching states per switching cycle, the repeated asymmetric sequence of switching states comprising at least three switching states selected from a group consisting of five defined switching states, the five defined switching states including an idle state.
