전장품 모듈레벨 EMC 최적화 기술 연구

As more vehicles become equipped with advanced electronic control systems, more consideration is needed with regards to automotive safety issues related to the effects of electromagnetic waves. Unnecessary electromagnetic waves from the antenna, electricity and other electronic devices can cause problems with the performance of automotive components, and with automotive safety. As a research for usual noise problem, PI(Power Integrity) or SI(Signal Integrity) analysis has been progressed a lot lately, however these analyses have stayed PCB level. Theses analysis methods are very different form EMC RE TEST circumstances therefore its results are a lot different from measured value. This paper proposes EMC optimization technology for analysis method closed to fundamental EMC circumstances. If module level EMC analysis which is proposed in this study can be applied to all automotive electronics systems, the inflow of unexpected EMC noise will be prevented.
