Comparative Analysis of DC-DC Converter Topologies and MPPT Techniques Used in SPV Based Water Pumping System Using BLDC Motor

Abstract

This paper deals with comparative analysis of DC-DC converters and MPPT Techniques BLDC motor driven water pump powered by Solar Photovoltaic Array (SPV). The better selection of DC-DC converter and suitable MPPT techniques is important for maximum utilization of Solar Photovoltaic (SPV)array power and soft starting of BLDC motor. The two prevalent MPPT Techniques, Incremental conductance (INC)and Perturb and Observe (P&O)are uses and their result is compared under changing climate condition. This work also compares the two DC-DC converters i.e. Buck-Boost and Cuk for 3–0 VSI connected BLDC motor and their result demonstrate that Incremental Conductance (INC)with the Cuk converter is a compatible combination for Solar Photovoltaic (SPV)based water pumping system.
