Abstract: Conventional PWM techniques generate acoustic noise because of high energy concentration around harmonics of switching frequencies. To reduce the acoustic noise the magnitude of harmonics around switching frequencies are to be reduced. In this paper three different types PWM techniques are proposed for the reduction of acoustic noise. The implementation of these PWM techniques is carried based on carrier comparison approach It is observed that carrier comparison approach is easy to implement when compared with space vector based PWM techniques. The performance evaluation of these PWM techniques are carrier out in MATLAB/Simulink and results are presented.
