Pv Fed Boost Spwm Inverter Driven Single-Phase Induction Motor,

摘要

PV array is increasingly employed for water pumping system. In this paper, a boost converter to step up the input voltage of the inverter interposed between the PV array and single-phase induction motor is developed. The model was implemented using MATLAB/Simulink with SPWM controlled inverter model. The detailed modeling of the components of proposed scheme has been taken up. The developed boost converter steps up the voltage produced by the PV array to a value which is suitable to run a single-phase induction motor. The inverter converts DC to AC is controlled by using sinusoidal pulse width modulation (SPWM) technique. By using a LC-filter pure sine wave is obtained which can be directly used to drive a single-phase induction motor. Experimental investigation presented gives the utility of such a drive system
