Introduction
This project designs an induction motor drive powered by a solar photovoltaic (PV) system for water pumping applications, integrated with a battery backup for continuous operation. It employs a novel analytical Maximum Power Point Tracking (MPPT) algorithm to optimize power extraction from the PV array under varying irradiance conditions. The system uses V/f control for the induction motor to maintain speed and torque suited for water pumping, while the battery backup ensures reliability when solar power is insufficient.
