Description
Summary:PV array is increasingly employed for water pumping system. In this project, a controller to vary the amplitude of the inverter output voltage interposed between the PV array and single phase induction motor is developed. The detailed modeling of the components of proposed scheme has been taken up. The developed controller varies the pulse-width of a SPWM generator, so that that the inverter output voltage varies with irradiation and temperature. The variation of the amplitude is to maximize the power output (speed) for a given irradiation and temperature. Experimental investigation presented gives the utility of such a control approach.
