電子設(shè)備電源的保護(hù)電路設(shè)計(jì)

摘要：隨著電子設(shè)備的集成度越來(lái)越高和功能越來(lái)越強(qiáng)，對(duì)電子系統(tǒng)的可靠性、穩(wěn)定性和安全性的要求越來(lái)越高，所以對(duì)電路保護(hù)的要求也越來(lái)越高。本文詳細(xì)介紹電子設(shè)備電源故障原因，列舉了工程中常見(jiàn)的保護(hù)電路和新型器件，提出了建立保護(hù)電路的模型，構(gòu)建了典型保護(hù)電路的設(shè)計(jì)方案。 敘詞：保護(hù)電路，過(guò)壓，過(guò)流，浪涌 Abstract：With the integration of electronic devices is getting higher and higher and more powerfulThe electronic system reliabilitystability and security have become increasingly demanding increasingly high requirements for circuit protection.
