Abstract: In the recent days most of the industries uses Induction motors as the primary loads. In order to meet the total load requirement multiple motors are used. In this paper two Vector Controlled (VC) Induction Motors and a double closed loop PWM rectifier are used to explain the operation of Master Slave Configuration. The work mainly concentrates on the operation of a Unity Power factor Controlled (UPFC) PWM Rectifier as the input source for both the Vector Controlled Induction Motors. This UPFC PWM Rectifier uses two closed loop pi control algorithms the inner loop controls the current and the outer loop controls the DC voltage. The proposed model is simulated in Matlab/ Simulink and the results shows good synchronization for two induction motors operated in master slave configuration.
