Analysis of Impact of Firing Angle on an AC Chopper in Terms of Harmonic Distortion & Power Factor
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.
Keywords
