摘要

本文报道了当普通低压电源的交流电源受到各种类型和程度的谐波畸变时，其响应的试验。这种扭曲可能是对设施进行电磁干扰攻击的一种可能形式。研究发现，开关模式电源不受这种攻击，但整流型电源非常容易受到影响，如果畸变不对称。

AC harmonics effects on small external power supplies (wall warts)

This paper reports on tests performed to determine the response of common low voltage power supplies when their AC power feed is distorted by various types and levels of harmonic distortion. Such distortion could be a possible form of IEMI attack on a facility. It is found that switched mode power supplies are immune to such attacks, but rectifier type supplies are very susceptible, if the distortion is not symmetrical.
