Space-vector-modulated three-level inverters with a single Z-source network [PDF]
The Z-source inverter is a relatively recent converter topology that exhibits both voltage-buck and voltage-boost capability. The Z-source concept can be applied to all dc-to-ac, ac-to-dc, ac-to-ac, and dc-to-dc power conversion whether two-level or ...

Z‐source‐based isolated high step‐up converter
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 ...
