Analysis, design, and implementation of switched Z‐source inverter with an extra control input

The current study proposes a topology for switched Z-source inverter. In the switching method used this structure, unlike conventional, active network switches’ duty cycle is not equal to shoot-through cycle. So, in addition cycle, of impedance switches also involved boost factor. Besides, by extracting small-signal model, it observed that proposed has two control inputs on dc-side. advantage additional input demonstrated designing closed-loop case where inverter as an interface between photovoltaics (PV) and grid. addition, steady-state analysis different operating modes pattern are presented topology. Comparing number elements factor with several conventional topologies indicates besides advantage, higher voltage gain. Finally, simulation experimental results verify theoretical discussions
