This study proposes a resonant switched capacitor voltage multiplier with a novel switching strategy. The proposed implementation provides a high voltage gain in comparison with other traditional approaches, this is achieved by charging every capacitor with the voltage of all previous charged capacitors. A safe commutation procedure is also presented in which switching errors are avoided regardless of variations in the resonant frequency, variations in the resonance frequency may be caused by tolerance in passive components. The converter offers the capability to drain resonant current through all switching devices using a single small inductor, the input current is continuous. A design‐oriented analysis of steady‐state waveforms is discussed through the study. To validate the proposed approach, experimental results are shown.
