Proposed New Method to Measure Common-Mode Current on High Frequency Circuits

Ahmed O. Mohmed

Abstract: It goes without saying that electromagnetic compatibility (EMC) is very significant in our life. Therefore, measuring common-mode current will estimate how much electromagnetic waves are emitted from the specific device. This paper has reviewed two methods to measure the common-mode current (CMC), these methods are very useful help to comprehend the experiments of standard (EMC) tests. These reviewed methods have used spectrum analyzer in order to show the result of the measurements unlike the proposed method in this paper. Whereas, a steps of designing and calibrated a tool that can measure the magnitude value of the (CMC) are covered in this article. The different between the first and second reviewed method for measurement of (CMC) is that both of them use spectrum analyzer but, the proposed methods uses (LCD display) so it makes the designing tool would be portable to do the measurements, so no need to do it in the lab
