DC-DC multiplier boost converter with resonant switching

•Resonant mechanism for multilevel boost converter improvement.•A charge interchange approach used to calculate capacitors in the steady state.•The voltage ripple on capacitors not dependent on the current waveform.•High efficiency obtained on the converter for that voltage gain.

This paper proposes an improved Multilevel Boost Converter, also known as Multiplier Boost Converter, in which the spike-type current among capacitors is eliminated through one resonant inductor, achieving some resonant-type current waveforms. Experimental results demonstrate the applicability of the proposition.
