Authors: C. Harikrihsna and T. Bramhananda Reddy and J. Amarnath and S. Kamakshaiah
Abstract: This paper presents a simple and novel generalized PWM algorithm for n-level multilevel inverter fed direct torque controlled induction motor drives. The proposed algorithm does not use the angle and sector information and hence reduces the complexity involved in the PWM algorithm. The proposed algorithm has been developed by using the concept of imaginary switching times, which are proportional to the instantaneous phase voltages only. The proposed algorithm generates the modulating waveforms for a n-level inverter, which will be compared with the level shifted triangular carriers to generate the switching pulses to the inverter. To validate the proposed algorithm several numerical simulation studies have been carried out and results are presented. From the simulation results, it can be observed that the proposed algorithm gives reduced harmonic distortion with increased number of levels.
