Harmonics in opposed current converters
IECON 2012 - 38th Annual Conference on IEEE Industrial Electronics Society, 2012Practical switching devices have finite turn-on and turn-off times. Normally a blanking time is added between the turn-off and turn-on of switches to avoid a short circuit during switching. This blanking time results in a current dependent voltage error of the pulse width modulated output of a converter.

Second harmonic of the acoustoelectric current in piezosemiconductors
Physica Status Solidi (a), 1980The second harmonic of the acoustoelectric current generation J(2ω) as a consequence of electronic concentration nonlinearity during the propagation of elastic waves at frequency ω in piezosemiconductors is investigated both, theoretically and experimentally. Bulk waves and waves in the acoustic waveguides are considered. It is shown that the current J

Proceedings of the IEEE International Conference on Industrial Technology (ICIT'96), 2002
New compensation method of specific number harmonics currents is proposed and its excellent compensation effects are explained in comparison with conventional versatile compensation. In addition, preference compensation of specific number harmonics currents is also proposed and experimental data with a small model proves the superiority of this method.

Harmonics in transformer magnetizing currents
Proceedings of the American Institute of Electrical Engineers, 1915The purpose of this paper is to show in a concise manner the cause and effects of higher harmonic currents in magnetizing currents of transformers. A hypothetical case is analyzed to show the cause of the harmonics; then the schemes of connecting transformers that are commonly used for polyphase transformation are taken up and the effects of the ...
