Othman A. The methods and tools to ensure the electromagnetic compatibility of semiconductor converters of audiosystems

The thesis is devoted to solving important scientific and technical problem, which is to develop methods and means to ensure electromagnetic compatibility of audio systems. The analysis of sources of interference in audio systems are present. Defined restrictions on insertion losses of RFI filters. The method for adaptive setting highs NRF response to harmonic noise inherent audio content. An expanded range of adjustment of the basic parameters of mains smart RFI-filter. The concept of constructing such filters with real determination electromagnetic environment based on distributed remote computing. The simulation modeling of smart RFI filter of audio system are developed. Refined mathematical model links RFI-filter that facilitates engineering analysis to implement parallel processing of data. An application interface of audio systems cloud computing technology, it is possible to personalize and simplify configuration anti RFI means that it is important in a real electromagnetic environment.The proposed several options for the technical means to ensure EMC of semiconductor converters of audio systems as a local application, and as part of an ensemble of complex audioequipment various purposes, such as a cinema complex or sound recording studio.
