In this work a PV (Photo Voltaic) array SEPIC fed single phase induction machine for water driving is demonstrated. A SEPIC employed to maintain continuous DC link voltage through governing duty cycle. A single phase induction motor drives the centrifugal water pump which is served by the output of the single phase inverter. Constant V/F SPWM (Sinusoidal Pulse Width Modulation) controls the single phase inverter. The variable solar irradiation obtains the performance of the proposed system. The SIMSCAPE and Sim Power System tool boxes is preferred for the MATLAB/SIMULINK environment for the modelling of water pumping system. The result of the system is examined and verified with simulation.
