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 ...
