Modulation-Based Harmonic Elimination
IEEE Transactions on Power Electronics, 2007A modulation-based method for generating pulse waveforms with selective harmonic elimination is proposed. Harmonic elimination, traditionally digital, is shown to be achievable by comparison of a sine wave with modified triangle carrier. The method can be used to calculate easily and quickly the desired waveform without solution of coupled ...

IEEE Transactions on Industrial Electronics, 2010 In this paper, the elimination of harmonics in a cascade multilevel inverter by considering the nonequality of separated dc sources by using particle swarm optimization is presented. Solving a nonlinear transcendental equation set describing the harmonic-

IEEE Transactions on Biomedical Engineering, 1978
A 60-Hz harmonic eliminator has been designed to remove dc and 60-Hz line frequency and its harmonics. By triggering a 1024-point sliding average on each cycle of the line voltage, the harmonics of 60 Hz and dc are averaged from the input. This average is then substracted from the input to eliminate these components, leaving the rest of the signal ...

Elimination of Supply Harmonics
IEEE Industry Applications Magazine, 1997The price of the extensive use of power electronic devices is becoming clear: increasing harmonic "pollution." The greater amount of harmonics being introduced into power distribution systems is of concern to both power consumers and power companies. First, a brief look is taken at background information which describes harmonic sources, effects, and ...

An overview on harmonic elimination
2015 IEEE International Conference on Mechatronics and Automation (ICMA), 2015As the distributed network technology develops, so do the grid harmonic problems, which were mainly caused by extensive using of power electronic devices and nonlinear loads. As far as the harmonic elimination, the filter which had been used widely can improve power quality of the network effectively.

Elimination of harmonics of multiconverters
CCECE '97. Canadian Conference on Electrical and Computer Engineering. Engineering Innovation: Voyage of Discovery. Conference Proceedings, 2002The suppression of higher harmonics is realised due to the increase of the pulsation index p of multiconverters. Two principal methods are known of the increase of p: the method of introducing the angle of phase difference between the primaries and secondaries of the transformer feeding the converters, and the increase of the number of phases q ...

Extension of real time harmonic elimination theory to the traditional selective harmonic elimination
2016 8th International Conference on Modelling, Identification and Control (ICMIC), 2016Generally speaking, almost the existing method used to implement the selective harmonic elimination in real time based on look-up table, which will consume lots of memories of the embedded processor. This paper propose a method that extends the real time harmonic elimination strategy based in modified carrier signal theory to the results obtained by ...

A Strategy for Eliminating Harmonics in Three-phae System with Harmonic Generators
2021 IEEE 4th International Electrical and Energy Conference (CIEEC), 2021A strategy for eliminating harmonics from the output of three-phase inverters is proposed with an idea of a special harmonic generator, which is characteristic in structure with a multi-phase round-shaped transformer for synthesizing the desired harmonics electromagnetically.

A Complete Solution to the Harmonic Elimination Problem
IEEE Transactions on Power Electronics, 2003The problem of eliminating harmonics in a switching converter is considered. That is, given a desired fundamental output voltage, the problem is to find the switching times (angles) that produce the fundamental while not generating specifically chosen harmonics.
