摘　　要：本文通过对各种热插拔控制策略的研究,针对新一代高性能计算机系统采用的12V直流母线供电结构,对该系统刀片式插件进行热插拔电路设计。采用最新的具有PMBusTM通信接口的控制技术实现了对刀片式插件电源总线的测量、保护和控制,并对电路进行了实验测试。该设计技术将应用于新一代超级计算机各类插件板上。After a variety of hot swap control strategies are studied,this paper intends to design a hot swap circuit for the blade plugqns with 12V power bus structure of the new generation high performance computer system. With the PMBusTM communication interface of the latest control technology,the measurement,protection,control and test of the hot swap circuit for the power bus of the blade plug-ins has been realized in this paper. The design techniques will be applied to a new generation of super computer plug-in boards.
