電子設備電源的保護電路設計

摘要：隨著電子設備的集成度越來越高和功能越來越強，對電子系統的可靠性、穩定性和安全性的要求越來越高，所以對電路保護的要求也越來越高。本文詳細介紹電子設備電源故障原因，列舉了工程中常見的保護電路和新型器件，提出了建立保護電路的模型，構建了典型保護電路的設計方案。 敘詞：保護電路，過壓，過流，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. This paper describes thecause of the failure of electronic equipment power supplyciting the projectthe protection circuit and a new devicea protection circuitmodel to construct a typical protection circuit design.
