Development of Standard Models for EMC Simulation

摘要

In this report, the group activity of developing and proposing standard EMC models for numerical EMC simulation is presented. Our group has developed some basic and standard EMC models which contain the essential characteristics of EMC and has discussed about the calculated behaviors. These models can be used for studying EMC and EMC simulation and for comparing different simulators. The developed models are briefly presented. A model of differential transmission lines, for example recently took up, is explained as an example. The differential transmission line which has a difference in height on the middle of the line was developed to investigate the emission depending on the parameters of line height, line separation, phase of the driver and so on. For example, the contribution of the common and differential mode radiation was studied by changing phases of the differential drivers. From the calculated results, it is suggested that the emission from the line was dominated common mode radiation because the emission was almost proportional to common mode voltage of the differential drivers.
