摘要

提出了一种测量PCB铜线间电场耦合的新方法。这种方法可以从面包板原型中获得的波形中测量噪声,这可以在设计过程的早期阶段使用。然后可以分析测量结果并为进一步的PCB设计提供信息。实验验证了该方法的有效性,并将其应用于离线反激变换器。

A method to measure EMI due to electric field coupling on PCB
A new method to measure electric field coupling between PCB copper traces is presented. This method enables measurement of noise from waveforms obtainable from breadboard prototypes, which is available in an early stage in the design process. The measurement result can then be analyzed and provide information for further PCB design. This method is verified by experiments and applied to an off-line flyback converter.
