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.

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 ...

Selective harmonics elimination: PWM method versus optimized total harmonic distortion
4th International Conference on Power Engineering, Energy and Electrical Drives, 2013This paper describes two different PWM methods to improve the quality of the output voltage waveform provided from five level inverter. The first one is the selective harmonics elimination (SHEPWM). The purpose is to cancel the 5th, 7th and 11th harmonic row.

Total harmonic distortion analysis simulation
PowerCon 2000. 2000 International Conference on Power System Technology. Proceedings (Cat. No.00EX409), 2002Using digital filters and MATLAB software to find out the harmonic components, the work is based on using Butterworth band pass filters with the corresponding cutoff frequency. In this paper, the authors use the idea of using digital filters to analyze and compute the frequencies of the harmonics.

Low Total Harmonic Distortion Quadruple Gain Boost Inverter
IECON 2019 - 45th Annual Conference of the IEEE Industrial Electronics Society, 2019This paper proposes a DC-AC converter capable of delivering pure sinusoidal voltage and current to resistive as well as inductive load. The proposed converter provides a quadruple boost while converting low-level DC input to high voltage low total harmonic distortion (THD) AC voltage.

(Invited) Total Harmonic Distortion for PEM Fuel Cell
ECS Transactions, 2017Electrochemical Impedance Spectroscopy (EIS) is well developed and widely applied for the study of electrode/electrolyte interfaces, films, coatings, and ion-transport mechanisms, among others. Measurement and analysis of traditional EIS is based on linear response in voltage or current to a sinusoidal perturbation.

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.

Indirect Measurement of Total Harmonic Distortion
SAE Technical Paper Series, 1990<div class="htmlview paragraph">Several methods of indirectly measuring total harmonic distortion (THD) in a power amplifier by measuring characteristics of the input and output waveforms are presented. The relative accuracies of each method is discussed. While the emphasis is on practical methods that can be implemented in a automobile car radio,

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)
