PS-04 Analysis of the EMI Filters in the Power Supply System for Electromagnetic Compatibility of Conduction Emission Test

This study originates from the standard CISPR 22 for measuring electromagnetic emissions. A power supply is chosen as the equipment under test (EUT) for the conduction emission (CE) test. The test results are also verified by the common mode (CM) and differential mode (DM) attenuation at the specified frequencies deduced by the physical circuit under the different selections of X- and Y- capacitors of the filter circuit in the EUT.
