Abstract

The growing demand for renewable energy solutions has led to the development of efficient solar-powered systems for agricultural and rural applications. This paper presents the design and implementation of a solar photovoltaic (SPV) array–fed water pumping system using a Brushless DC (BLDC) motor and a Zeta DC–DC converter. The system utilizes a Zeta converter to boost the low and variable output voltage of the solar panel to a regulated level suitable for driving a BLDC motor. A three-phase Voltage Source Inverter (VSI) is used to convert the DC output into AC supply for the motor. A PIC microcontroller generates switching signals for the inverter, enabling efficient motor operation and soft starting. The proposed system offers improved efficiency, reduced starting current, and low power losses. Experimental results demonstrate reliable operation and suitability for standalone water pumping applications in rural and remote areas.
