Coupled‐inductor‐inverse high step‐up converter
IET Power Electronics, 2018 This study presents a novel high conversion gain converter with a tightly coupled‐inductor‐inverse for distributed generation system, where high conversion gain is regularly required. The new converter utilises coupled‐inductor‐inverse network for high conversion gain applications that is not presently comparable with the existing coupled inductor ...

High‐step‐up enhanced super‐lift converter
IET Power Electronics, 2020 This study proposes a new high step‐up DC–DC converter based on a novel super‐lift structure and coupled inductor. The energy stored in the leakage inductance of the coupled inductor is recovered to the converter output, which leads to a snubber‐less operation and consequently a fewer‐component, lower‐cost and more‐efficient converter.

Coupled‐inductor‐based high step‐up DC–DC converter [PDF]
IET Power Electronics, 2019 A novel high step‐up DC–DC converter with coupled inductors has been proposed. The proposed topology includes two coupled inductors, four capacitors, four diodes, and two metal–oxide–semiconductor field‐effect transistors. Two coupled inductors charge in parallel when the switches are on and discharge in series when switches are off.
