Comparison of integrated and composed step-down converter in terms of EMC

Abstract

Stabilized voltage sources, even linear or working on a switching principle, are an integral part of almost all electronic devices. Hand in hand with the pressure of environmental protection, there comes an emphasis on reducing energy consumption, resulting in preference of switching solutions. On the other hand, considering the issues on electromagnetic compatibility, each switching-mode operated power source produces considerable amount of interferences. In the framework of the hereby described experiment, the authors of the paper tested several voltage sources operating on the switching principle. This paper provides a description of the experiment and the obtained results. © The Authors, published by EDP Sciences, 2017.
