Abstract

In this paper, a software-based common mode (CM) and differential mode (DM) measurement system for the conducted EMI is presented. A user friendly interface is developed to provide an effective communication between the user and the system. The panel of the spectrum analyzer can be displayed on the PC screen and adjusted with the keyboard or the mouse by the user. Either CM or DM noise can be calculated from the other measured result. Experiments show that the proposed system works well
