CONTROLLING OF PV FED BLDC MOTOR USING AN OPTIMIZATION ALGORITHM

In order to maximize the efficiency of an SPV array and accomplish soft starting of apermanent magnet blushless DC motor this study deals with a buck-boostconverter driven solar photovoltaic array fed water pumping . Current sensors which are typically used to regulate the speed of BLDC motor are entirely removed. A voltage-source inverter’s changing DC-link voltage controls the BLDC motor’s speed (VSI). This study examines how the interleaved DC-DC converter which serves as a transitional DC-DC converter between the solar PV array and soft starting of BLDC motors operates in a solar PV array fed water pumping system. The output ripple current of the intermediate region for recording maximum power (MPPT). In this project the speed of a brushless DC motor has been managed by utilizing a variety of control approaches including PI Fuzzy and PSO optimization techniques. To get the most efficiency out of the solar array the system is powered by a solar PV array and the MPPT technology.
