Ripple‐Free Input Current Quadratic Converter Based on Watkin–Johnson Topology
IET Power Electronics, Volume 18, Issue 1, January/December 2025.This article proposes a power electronics converter capable of providing high voltage gain while keeping a high‐quality input current ripple. The technique for achieving the zero input current ripple at a selected duty cycle consists of extracting two inductor currents from the source in a counter‐phase manner.
