Single-inductor resonant switched capacitor voltage multiplier with safe commutation

This paper proposes a resonant switched capacitor voltage multiplier with a novel switching strategy a high voltage gain, and a safe commutation procedure regardless of variations in the resonant frequency. The converter offers the capability to drain resonant current through all switching devices using a single small inductor. A design-oriented analysis of steady-state waveforms is discussed through the paper. Experimental results are shown in order to validate the proposed approach.
