In this paper a new closed loop control of induction motor fed by a Z Ã¢â?¬â?œ source inverter based on the vector control or field oriented control strategy is presented. Induction motor is supplied by Z Ã¢â?¬â?œ source inverter, in the Z Ã¢â?¬â?œ source inverter the term Z denotes impedance which means a combination of L & C element which are cross connected. The Z-source inverter consists of a unique impedance network (or circuit) to couple the inverter main circuit to the power supply, hence providing great features that cannot be observed in the conventional voltage-source inverter and current-source inverters in which capacitor and inductor are used, respectively.In the field oriented control method or vector control method speed of the induction motor, torque & 3 phase stator current is given to the field oriented controller and gate pulses for the inverter is generated to obtain the desired operation of the induction motor.
