Analysis of Power Quality in Various Power Supplies Using MATLAB

Electronics and Commutation Engineering

Power supplies are being used extensively in various electrical and electronic applications. In which AC to DC rectification and filtering action has been done with the advantage of high efficiency and power density. Thus we can say that the main problem associated with power supplies is the injection of harmonic current into the supply, which has adverse effects on the system performance and more importantly can also cause poor power factor. Due to stringent power quality regulation and supply regulated by Standards V, 2, IEC 61000-3-2 and IEEE 519-1992 which imposes strict constraints on total harmonic distortion ion, research at the utility interface for better power quality shows importance. The power quality of the power supply is simulated and analyzed by measuring total harmonic distortion and power factor. Through which various power supplies will be analyzed using MATLAB.
