语言:

中文摘要

随着高功率密度电源适配器设计的发展,组件间距缩小导致近场耦合问题加剧,严重影响了高频下的电磁干扰(EMI)滤波性能。本文深入研究了近场电容耦合机制,并提出了相应的抑制技术,以优化高密度电源系统的EMI性能。

English Abstract

In consumer electronics, high power density power adapters are designed to minimize the adapter size. As a result, the components are getting very close and the near-field coupling issue tends to be severe. This compromises the performance of electromagnetic interference filters, especially at high frequencies. This article investigates near-field capacitive couplings and the reduction techniques ...
