Harmonic Assessment Based Adjusted Current Total Harmonic Distortion [PDF]

open access: yesThe Journal of Engineering, 2016
Power systems suffer from harmonic distortion and extra ohmic losses associated with them. Moreover, all harmonic frequencies are mostly assumed to have the same effect on the system losses. However, the frequency-dependency of the resistances should be

Total Harmonic Distortion Factor Evaluation in Shipboard Electrical Networks

open access: diamondScientific Bulletin of Naval Academy, 2018
Electric propulsion systems for modern civil and military ships, as well as the growing number of electric consumers on board, are a topical issue in terms of onboard electric power quality. In this respect, a growing number of high power static converters are used, which inevitably leads to the appearance, in the electricity distribution network, of ...

Reduction of total harmonic distortion in power inverters [PDF]

open access: yes, 2005
The output voltage of PWM power inverters shows harmonic distortion due to several causes; the main ones are the modulation algorithm, nonlinearities in the output filter, dead times, voltage drops across the switches and modulation of the dc bus voltage.

Total Harmonic Distortion Minimization of Multilevel Converters Using Genetic Algorithms

open access: diamondApplied Mathematics, 2013
This paper presents a genetic algorithm (GA) optimization technique to find the optimum switching angles of 11-level inverter with minimum number of dc sources and switches in comparison with the cascade multilevel inverter in order to minimize the total harmonic distortion (THD) of their output voltage waveform.
