In this paper, under varying the temperature and irradiance, the comparison between single stage and two stage conversion of PV system using LabVIEW has been 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. PV cell, inverter and induction motor have 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
