Solar water pumping system employing induction drive with high level boost converter

This paper deals with a water pumping system which is powered by PV (Photo Voltaic) cell. A high level boost converter topology is being used between solar panel and the PWM inverter. The DC link voltage is maintained constant by controlling the duty cycle of the high level boost converter. Water pump is being driven by induction machine which is fed with the output of the high level boost. Performance of proposed system is obtained under fixed solar irradiation. The water pumping system is modelled in MATLAB/ SIMULINK environment using the Sim Power System and SIMSCAPE tool boxes. The performance of the system is analysed with both simulation and experimental setup. Real time simulation has been carried out using dSPACE 1103.
