Prediction of the common-mode radiated emission from the board to board interconnection through common-mode antenna model

In this paper, the common-mode antenna model, which can estimate the amount of common-mode radiation quickly and accurately, was applied to a board-to-board interconnection structure with a connector. The inductor model is introduced as the connector model for improving accuracy of the common-mode antenna model. By using the inductance, which was calculated with the commercial electromagnetic field simulator, the radiated emissions estimated by the model agreed with the measurement results within an error of 3 dB around the peak emission levels.

Overview of component level EMC characteristics for HEV application

This article presents the power point presentation on the overview of component level testing for HEV products and simulating actual vehicle condition at component-level that would be the most important. A fundamental study of the emission from HV system was calculated and characterized with consideration of effects from HV related typical parameters. The noise source and effects of low voltage system was investigated, with the necessary consideration of coupling between LV and HV system.
