MPPT Based Solar PV and Class IV Powered Brushless DC Motor for Water Pump System

In this work the PV (Photo Voltaic) panel is used for primary energy supply of the complete arrangement. However, class IV power supply is proposed as a backup power source. The PV output power is fed to zeta converter and class IV source is fed to boost converter with the same input power. In this proposed system the P&O algorithmic method of MPPT is implemented. The P&O algorithm regulates the duty cycles given to zeta converter, that will continue DC link voltage. The motor speed is regulated by correcting the voltage of the DC link in the inverter which is given to motor. When the PV power absent, class IV power and boost converter maintain the voltage constant across DC link. The effectiveness of proposed work can be verified using MATLAB simulation and developed prototype model.
