Abstract :
Line noise filters are used to suppress conductive noise of electrical machinery and apparatus. In general, this filter composition is chosen by a trial and error method. Therefore, in order to carry out a theoretical design of the line noise filters, we studied an equivalent circuit for the line noise filters using the attenuation characteristic of the filters. As a result, we found that we can derive an equivalent circuit for line noise filters which is similar to actual filters, by means of adjusting the parts element of the filter
