This paper presents a case where such a drive is identified as a flicker source as well. A VFD causes voltage flicker due to the fact that it is an interharmonic source. The interharmonics could beat with the fundamental frequency component, resulting the generation of voltage flicker. Through field measurements and simulation studies, this paper explains how a VFD causes voltage flicker problems and the various factors that have an impact on the flicker generation characteristics of a VFD. This paper can serve as a useful example to guide people who need to troubleshoot voltage flicker problems.","PeriodicalId":406398,"journal":{"name":"2004 11th International Conference on Harmonics and Quality of Power (IEEE Cat.

The active power filter provides compensation currents in such a way that the utility supplies only the balanced fundamental frequency current at unity power factor, even if the load draws reactive and harmonic currents. The proposed scheme does not need to sense utility voltages, thereby reducing the complexity. In this paper, UCI control is applied to both four-leg and three-leg inverter topologies. The effectiveness of the proposed scheme is demonstrated by the simulation results.","PeriodicalId":406398,"journal":{"name":"2004 11th International Conference on Harmonics and Quality of Power (IEEE Cat.

In second place, the principle of identification of the harmonic currents by the method of the instantaneous powers real and imaginary is developed, followed by the presentation of the new optimized SVPWM strategy control applied to the inverter of the active filter. A strategy which makes it possible to order the inverter of the filter to generate the harmonic currents required with the optimization of the number of commutation of the semiconductors used.
