Analysis of impact of firing angle on an AC chopper in terms of Harmonic Distortion & Power factor Chaturvedi Kanchan1,*, Dr. Mahor Amita1, Dwivedi Anurag Dhar2 1Department of Electrical & Electronics Engineering, N.R.I., Bhopal (M.P.)

Online published on 4 November, 2017. Abstract The phase angle controlled AC choppers are widely used for voltage regulation & controlling. Apart from the advantages of method such as low cost I Simple construction, easy operation it has a major disadvantage of inducing Harmonic components & power factor even with pure resistive load. Hence in this paper we are analyzing the various aspects of AC choppers by Simulation & mathematical analysis. The AC chopper considered in this paper is symmetric & the Switching devices are considered to have ideal Switching characteristics for mathematical Analysis. The Simulation & graphical analysis are performed in MALAB/Simulink. Top Keywords AC choppers, Harmonic Distortion, Power Factor. Top | |
