This paper has discussed the effect of harmonics on the power quality of the power supply.  The paper also discussed the different configurations of PWM techniques for harmonic reduction and improvement of fundamental peak voltage. In addition, a comprehensive comparison of all configurations is made in terms of THD, FFT and dominating harmonics components. This paper describes the results on the basis of MATLAB simulation. It is shown how, with suitable modifications. The conventional Regular Sampled PWM technique can be simply extended to allow Harmonic Minimization and also Harmonic Elimination PWM to be closely reproduced using simple algebraic equations. This survey paper will provide the insight of trends and technology of “Power Quality Improvement using PWM Technique.
