The single-switch voltage equalizer with Quasi-Z-Source inverter for partial shading is proposed. The occurrence of multiple maximum power points in the PV system is settled, and the partial shading issue is focussed. Various parameters like output voltage of the converter, voltage gain and efficiency are analysed for the proposed system. The efficiency of the proposed system is 94% with a proper voltage balancing. The performance comparison between the ZSI and Q-ZSI is made validating the Q-ZSI for the PV application. The implementation of a 20 W system is made, and its results are tabulated.
