•A switched capacitor voltage multiplier with resonant current between capacitors is presented.•A safe commutation strategy is explained.•The proposed converter provides interleaving capability and soft switching.•The proposed converter contains a reduced number of components. This paper presents a switched capacitor voltage multiplier with resonant-type current between capacitors; these current waveforms are achieved by designing a resonant topology combined with a safe switching strategy. Moreover, the proposed converter provides interleaving capability, soft switching, modular structure and a reduced number of components. These features yield a low cost converter with high voltage gain scalability, reduced input current ripple and limited peak currents between capacitors. Experimental results that corroborate the advantages of the proposed topology are presented.
