摘要
分析了开关电源产生电磁骚扰的原因,从控制骚扰源的骚扰强度,切断或衰减骚扰传播途经造成的影响两方面介绍了抑制骚扰的措施。
This paper analyses the sources of electromagnetic disturbance from switching-mode power supply,and introduces methods for suprressing it by means of controlling its strength and cutting off/attenuating the effect of its transmission paths.
