Equivalent circuit analysis of a noise-reduction transformer

摘要

This paper describes the equivalent circuit analysisof a noise-reduction transformer. The optimum design andquantitative analysis of noise-reduction transformers have not yetbeen clarified. To determine a method for realizing the optimumdesign of noise-reduction transformers, we discuss the noiseattenuation characteristics of the noise-reduction transformer onthe basis of both experiments and equivalent circuit analysis,taking account of the frequency characteristics of the circuitparameters. We also discuss the dependence of the noiseattenuation on the variety of load.
