This project presents a simple, cost-effective, and efficient brushless DC (BLDC) motor drive for a solar photovoltaic (SPV) array–fed water pumping system. The proposed system utilizes a Zeta DC–DC converter solely for voltage boosting, converting the 12 V output of the SPV array to a regulated 24 V DC supply required for operating a 24 V BLDC motor. The boosted DC output from the Zeta converter is supplied to a three-phase Voltage Source Inverter (VSI), which drives the BLDC motor connected to a water pump. Soft starting of the BLDC motor is achieved by controlling the inverter switching frequency, thereby reducing the high inrush current during startup and protecting the motor windings from thermal stress. A PIC microcontroller is employed to generate the necessary gate signals for the three-phase MOSFET driver circuit of the VSI. By operating the inverter at optimized switching frequencies, the system minimizes switching losses and improves overall efficiency. The proposed system offers reliable operation, reduced starting current, low power loss, and economical implementation, making it suitable for standalone solar water pumping applications.
