Modelling of Antiphase Noise Reduction of a Transformer
This article discusses about development of research of using antiphase elimination of noise reduction. It dedicated to modeling of acoustic phenomena by software AnSys and possibility of simulation and modeling of acoustic short-circuit over the antiphase elimination. The team of authors of this article have been involved in the issue of eliminating noise emissions by electronic equipment from the year 2009. This theme is extremely relevant at present since the health of the human population is a definite priority in human efforts. The first functional prototype for an Antiphase Eliminator, which was installed on a power transformer, was successfully constructed in 2012 on the basis of research. The team develops anti phase eliminator for over 6 years. Now after completion of analog prototype began with digitization and thus building another prototype. This new prototype will processes the signals into digital form. Because the efficiency of the analog prototype is relatively low, the team began together with the digitization also work on computer models that would reveal possible causes of low efficiency. These models already subtracted signals only, as it was on the start of research. These models simulate real acoustic propagation in space, his reflections and the resulting impact of the action of antiphase eliminator.
