Abstract: In this paper, a direct load angle control (DLA) method of a three phase induction machine is proposed to minimize torque ripple and flux ripple while maintaining constant switching frequency. In this comparision between the DLA and DTC. In DLA control drawback of switching frequency is overcome by using SVM. Proposed DLA control method is applied to three level voltage source inverter fed induction motors and result is presented. From the simulation result it is found that the proposed DLA control scheme impressively reduced the torque and flux ripples when compared with conventional DTC.
