Comparative Study of PWM Inverters Fed 3-Phase Induction Motor
نویسنده
چکیده
In this paper the performance of three-phase induction motor, fed from SPWM & MSPWM inverters are discussed. Computer simulations are used to compare the performances. The 3 phase induction motor model is simulated with sinusoidal excitation. The line current, output power, and efficiency are compared with the experimental results. The simulated results are very close to the practical values and the difference is less than 10%. The torque developed by the motor, when fed with SPWM-inverter and that of MSPWM-inverter are compared. The distortion in the developed torque in both the cases is compared. From the simulation results it is observed that, the average value of torque developed by the motor is same when the motor is fed with SPWM and MSPWM inverters. But the distortion is less when the motor is excited with MSPWM inverter.
