摘　　要：为了解决高性能计算机分布式供电体系中间母线电压在热插拔状态下的可靠运行问题。对TPS2490热插拔控制器分析后进行了相关参数设计研究。设计出针对较高电压、大功率的热插拔电路,测试结果与预期相符,系统功能设计及性能要求已全部实现,解决了整个母线电压及系统的稳定性、可靠性问题,同时表明该系统具有供电质量好,可靠性高,易于维护等优点。For resolving reliable operation problem of the high performance computer distributed power supply system＇s bus voltage under hot swapping. This paper make the reserch and layout for the related parameter of the TPS2490 hot swappable controller by analyzing it. Devising hot swappable circuit aim to high electric voltage, big power, testing a result and expecting to agree with, the system function design and function request already all realizations, resolving the stability problem of the bus voltage and system, at same time that system has good power supply quality, high reliability, being easy to a maintenance advantages.
