【 摘 要 】

It has been found that by using Pulse with modulation technique can greatly reduce the harmonics distortions generated by the PV inverter. Harmonics reduction is the main consideration in three phase squirrel cage induction motor. We can improve the performance of the three phase squirrel cage Induction motor by the reduction of THD. In this research work, the harmonic distortion of the three phase induction motor was measured in terms of THD by Simulation model and the results of the Multiple Pulse Width Modulation and Sinusoidal Pulse Width Modulation inputs were compared to find out the lowest THD value. By using the PWM technique on the Three Phase Induction motor there was reduction in the VTHD. In order to select lowest THD value for a particular frequency, Neural Network tool are used. The selected modulation index and frequency is given to the input of the inverter circuit. At this condition we can connect the PV circuit to the grid circuit.
