摘要
电源瞬时波动是一种严重的电磁干扰源,能对微机产生严重的干扰和破坏。分析了电源瞬时波动形成的原因及其对微机系统的影响,提出了采用稳压电源、不间断电源和后备电源等防护措施,在此基础上,重点研究了利用系统本身功能消除电源瞬时波动造成影响的具体方法。
Power supply instantaneous fluctuation is a serious electromagnetic interference source,it can destroy and interfere the electronic system badly. The paper analyzes reasons of the power supply instantaneous fluctuation and the effects to microcomputer. The protection method of using regulated power supply, uninterrupted power supply,and backup power is proposed. Base on this,the effective protection steps are put forward.
