Comparative Study of Developed Torque in 3-phase Induction Motor Fed from Mspwm Inverter and Multilevel Inverter
In this paper the torque developed in three-phase induction motor, fed from MSPWM inverter & multilevel 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 difference in simulated results and the practical values is less than 10%. The torque developed by the motor, when fed with MSPWM-inverter and that of multilevel-inverter are compared. The distortion in the developed torque in both the cases is compared.
