This study deals with a buck-boost converter controlled solar photovoltaic array fed water pumping in order to achieve the maximum efficiency of an SPV array and the soft starting of a permanent magnet brushless DC (BLDC) motor. The current sensors normally used for speed control of BLDC motor are completely eliminated. The speed of BLDC motor is controlled through the variable DC-link voltage of a voltage-source inverter (VSI). This project deals with the operation of the interleaved DC-DC converter in solar PV array fed water pumping system as an intermediate DC-DC converter between the...

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...
