Authors: O. Chandra Sekhar, Dr.K.Chandra sekhar Member, IEEE
Abstract: In this paper a novel nine–level inverter system for Direct Torque Control (DTC) induction motor drive is presented. DTC strategy of a nine–level Multi Point Clamped (MPC) Voltage Source Inverter (VSI) fed induction motor is implemented. Nine-level MPC inverter is an advanced technology and are commonly applied to high power electrical drives instead of the two-level VSI .Nine-level inverter has 729 space vector switching states and there are 106 effective vectors are possible. The proposed nine-level inverter scheme is capable for enough degrees of freedom to control both electromagnetic torque and stator flux with very low ripple. From the simulation results shows that feeding electrical drive with nine-level inverter can greatly improves the drive performance as compared to the seven-level inverter. The performance of this control method has been demonstrated by simulations performed using a versatile simulation package, Matlab/Simulink
