Distortion: Total harmonic distortion in an asymmetrically clipped sinewave

IEEE Instrumentation & Measurement Magazine, 2011
The application of a signal to an electronic system such as an amplifier invariably results in an output that is, in some sense and to some extent, a distorted version of that input signal. The application to which the system is put is a major determiner of whether or not the distortion can be neglected or, at least, of how much distortion can be ...

Total Harmonic Distortion Decomposition Depending on Distortion Origin

IEEE Transactions on Power Delivery, 2005
The total harmonic distortion (THD) ratio is a well-known parameter that characterizes the distortion degree at a specific point of the grid. In this paper, a decomposition of the THD will be presented in order to determine the responsibility of the distribution company and the electrical energy consumer for the harmonic distortion measured at the ...

Measurement uncertainty in evaluating total harmonic distortion factor

IMTC 2001. Proceedings of the 18th IEEE Instrumentation and Measurement Technology Conference. Rediscovering Measurement in the Age of Informatics (Cat. No.01CH 37188), 2002
In the last years power quality issues have been growing in more and more interest, and therefore the definitions of power quality indices are of increasing concern. Obviously the validity of an index is tightly correlated to its measurement uncertainty.

Reduction of total harmonic distortion in electronic ballast

2017 International Conference on Innovations in Electrical, Electronics, Instrumentation and Media Technology (ICEEIMT), 2017
The main aim of this paper is to reduce the distortion produced in the output side of the AC mains of electronic ballast. The paper implies design of electronic ballast (EB) for compact fluorescent lamps (CFL) by replacing the conventional electronic ballast circuitry with improved SMPS and inverter topologies.

Application of Harmonic and Total Harmonic Distortion Instrumentation in Corrosion

2019
Linear polarization resistance and electrochemical impedance spectroscopy (EIS) are widely applied in corrosion for studying the electrode/solution interface, films, coatings, and corrosion rates. Most potentiostatic and galvanostatic EIS measurements are based on the use of a perturbation signal (i.e., frequency or amplitude modulation of a sine wave)

THE IMPACT OF SHUNT COMPENSATION ON TOTAL HARMONIC DISTORTION

International Journal of Power and Energy Systems, 2006
The objective of connecting shunt compensation at nonlinear load terminals is to reduce the displacement angle between the supply voltage vector and the fundamental supply current vector, thereby increasing the power factor. The important feature, however, is the effect on the total harmonic distortion of either voltage or current.
