Filter implementation as a means to enhance electromagnetic compatibility in chargers

Abstract

EMC stands for "electromagnetic compatibility," and it refers to the ability of electronic devices and systems to function properly in their electromagnetic environment without causing interference to other devices or systems. EMI stands for "electromagnetic interference", and it refers to the unwanted electromagnetic energy that can interfere with the normal operation of electronic devices and systems. Both EMC and EMI are important considerations in the design and operation of electronic devices and systems, as well as in the management of the electromagnetic environment. This is particularly true in the fields of telecommunications, aerospace, automotive, where electronic systems are often required to function in challenging electromagnetic environments. The concept of EMC has become increasingly important as electronic systems have become more prevalent and more integrated into all aspects of our daily lives. As a result, many national and international standards have been developed to help ensure that electronic systems meet minimum requirements for EMC and do not cause harmful interference. The goal of this paper is to find a way of improving conducted EMC regarding the CISPR 16 standard of a specific charger using different filters and to see how the spectrum behaves regarding the real-life counterpart of a car charger.This paper is organized in a way where firstly the problems of EMC are addressed, after which the experiment of the paper is explained, and in the end the results are shown and analyzed.
