Implementation of Solar Powered Brushless DC Motor Driven Water Pumping System using Quasi-Z Source Inverter

Abstract: This work deals with designing a brushless DC (BLDC) motor driven water pumping system powered by a Solar Photovoltaic (SPV) array with Quasi-Z Source Inverter (q-ZSI). The Induction motor (IM) driven water pumps can be replaced by the BLDC motor driven water pumps due to its several advantages over IM. Also, the Quasi- Z source Inverter has various advantages over Current Source Inverter (CSI), Voltage Source Inverter (VSI) and Z- Source Inverter (ZSI) as it provides better shoot through states which in turn provides a single stage power conversion. The propriety of the proposed system is cleared through its performance analysis using MATLAB/Simulink based simulated results.
