  Electronic equipment's require supply voltage with different values that can create a stabilized voltage at the output in the conditions of changing the source voltage and load current. The flyback switching converter is a suitable option for producing different voltages in such conditions. Due to the high frequency switching, the electromagnetic components with significant power are directed from the converter side to the power lines and also radiated to the surrounding space, which causes electromagnetic pollution and EMI radio interference. In this article, an effective and practical method for designing and adjusting the EMC electromagnetic compatibility filter is presented. Adjusting the filter values is based on averaging the noise circuit by considering its equivalent impedance. In most of the proposed methods for filter design, the noise source is assumed as an ideal current source and the equivalent impedance of the noise is not considered. This reduces the accuracy of the design and prevents the correct filtering of the components in some frequencies. In this article, the circuit averaging of the entire structure of the converter is done by considering the parasitic elements, because the closer the presented model is to the real structure, the more effective the filter is, and the more effectively it removes radio interference components. In the end, the software simulation shows the accuracy and efficiency of the proposed method in EMI filter design. Manuscript profile
