Comparison of Single Stage & Two Stage Conversion of PV System for VSI Fed Induction Motor Drive under Varying Temperature and Irradiance using LabVIEW

In this paper, the comparison of the single stage and two stage conversion of PV system under varying the temperature and irradiance using labview are proposed. Due to clean energy and less impact on the environment, now a day's solar energy is preferred most and represented by PV (photo voltaic) cell. PVcell, inverter and induction motorhave been designed using labview and the converter is designed using NI multisim. The simulated result shows the characteristics like torque, speed, current and flux by varying temperatures and irradiance. These results are presented and validated.
