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.

Robustness evaluation of transformerless PV inverter topologies [PDF]

2014 IEEE 15th Workshop on Control and Modeling for Power Electronics (COMPEL), 2014
Transformerless PV inverter topologies allow the PV inverter size and weight to be reduced while reaching a higher efficiency. The drawbacks of these topologies are that DC current components at the grid side must be cancelled by means of the employed controller and the number of power devices required to avoid currents through the parasitic capacitor ...
