PV powered quasi Z-source inverter for agricultural water pumping system

The PV powered Single Phase Quasi Z — Source Inverter proposed in this paper has the major advantage of turning out the output voltage to be either buck or boost added to the advantage of being in phase to the input voltage. Eliminating the role of snubber circuit, using safe commutation strategy in the proposed single phase Quasi Z — Source DC — AC inverter, the inverter will be able to operate under continuous current mode. Solar PV power generation technique is used to obtain maximum input voltage. A laboratory prototype is tested using a resistive load. This inverter has higher input power factor and efficiency compared to the conventional method. Elimination of voltage spikes is highly possible using safe commutation strategy. Proposed work is predominantly to focus on agricultural water pumping system.
