Integral function method for determination of nonlinear harmonic distortion
Solid-State Electronics, 2004 The analysis of harmonic distortion is of prime importance for the analog and mixed integrated circuits. Recently we presented a new integral function method (IFM), based on a completely new principle, which allows the calculation of harmonic distortion ...

Distortion: Total harmonic distortion in an asymmetrically clipped sinewave
IEEE Instrumentation & Measurement Magazine, 2011The 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, 2005The 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), 2002In 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), 2017The 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.

Impact of Load on Total Harmonic Distortion in a Photovoltaic System
2020 IEEE Asia-Pacific Conference on Computer Science and Data Engineering (CSDE), 2020Environmental concerns are the biggest reasons for the rising interest in Renewable Energy sources. Rapid industrialization and urbanization have forced engineers to look at cost-effective sources. Power quality issues are increasing day by day. The introduction of sensitive equipment into an electrical grid is an essential factor for the introduction ...

THE IMPACT OF SHUNT COMPENSATION ON TOTAL HARMONIC DISTORTION
International Journal of Power and Energy Systems, 2006The 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.

Application of Harmonic and Total Harmonic Distortion Instrumentation in Corrosion
2019Linear 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)

Current controller with low total harmonic distortion
2005 European Conference on Power Electronics and Applications, 2005A new digital current controller with active-null state modulation for voltage source inverter systems (VSI) is presented. The major advantages of the proposed current controller system are: minimisation of the total harmonic distortion (THD) of the output current waveform and maximisation of the time of application of the voltage ...
