| Abstract |
Due to the increasing use of fast switching semiconductors, emissions affected by the Adjustable SpeedDrives (ASDs) are entering the new frequency range of 2-150 kHz. Emissions at this new frequencyrange are categorised into 2-9 and 9-150 kHz ranges among the standardization communities.Consequently, designing new filters for theses frequency ranges is of the determined efforts by ASDmanufacturers. In this paper, essential factors impacting on the filter design in ASDs for 0-2 kHz andthe new frequency range of 2-9 kHz are investigated. Non-linear effects of DC link filter on low orderharmonic emissions of 0-2 kHz is investigated to understand how the existing filters can comply withthe emerging standard of 2-150 kHz. Moreover, a system model is presented to predict the effects ofcables and Electromagnetic Interference (EMI) filter parameters on resonances at the frequency rangeof 2-9 kHz. |
