摘要

本文基于电力电子学的基本电路和概念，提出了一个简化的传导电磁干扰工具箱。EMI工具包的简化结果是介绍了由无源元件的自谐振频率(SRF)、二极管的反向恢复时间、开关频率、栅极驱动控制、缓冲电路、散热器的寄生电容、EMI滤波、总谐波失真(THD)和传导EMI引起的传导EMI的影响。这些基本现象可以引导设计工程师和学生理解电磁兼容的概念，只关注传导发射，使用一步一步的实验。

Electromagnetic interference self-learning toolkit in switched-mode power supplies

This paper presents a simplified conducted EMI toolkit based on the basic circuits and concepts of power electronics. The simplified results of the EMI toolkit is to introduce the effect of conducted EMI caused by self-resonant frequency (SRF) of the passive components, reverse recovery time of diodes, switching frequencies, gate drive control, snubber circuit, parasitic capacitor of heat sink, EMI filtering, total harmonic distortion (THD) and conducted EMI. Those basic phenomena can lead designing engineers and students to understand the EMC concept, focused on only conducted emission, using step-by-step of the experiment.
