SIMULATION AND IMPLEMENTATION OF PWM INVERTER FED INDUCTION MOTOR DRIVE

G. Pandian, S. Rama Reddy

This paper presents Simulation of three phase PWM Inverter fed Induction Motor Drive using Pspice. The proposed induction motor drive model employs only seven switches and incorporates an active current shaping feature. The boost converter at the input can give the required voltage at the input of inverter. The boost converter also improves the power factor. The drive works satisfactorily at low input voltage since the boost converter maintains required voltage.
