This paper deals with the application of a single ended primary inductor converter (SEPIC) in solar photovoltaic (SPV) array fed water pumping system. A permanent magnet synchronous motor (PMSM) motor is employed to drive a centrifugal pump coupled to its shaft. A vector control PMSM motor is achieved by controlling the SEPIC through the incremental conductance maximum power point tracking (INC-MPPT) algorithm. The SEPIC possesses the merits of non-inverting polarity output voltage, simple gate-drive circuit and low input current pulsation. It can increase or decrease it’s output voltage according to duty ratio. This property provides the flexibility of optimizing the operating point of the SPV array at any voltage level. The outputs of the proposed system is verified through simulated results using MATLAB/ Simulink environment. Keywords— PMSM, Solar, SEPIC Converter, Water Pumping
