Z‐source‐based isolated high step‐up converter
IET Power Electronics, 2013 Continuous input currents and high step‐up ratios are desired from the dc–dc converters that work with renewable energy sources such as photovoltaic panels and fuel cells. Most dc–dc converters use transformers to have high step‐up ratios. There is another type of converters that use coupled inductors, but they need to operate at high duty cycles to ...

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.
