热插拔表示一个系统在输入端、输出端和信号总线都处于工作状态的情况下,安装或拆卸电源模块的能力。热插拔冗余电源系统增加了系统的容错程度,这对于要求紧急停机的系统格外需要。 为了实现一个热插拨电源系统,设计者应当深入了解一些电气方面的有关问题,比如冗余技术和电流共享,并且他还应当对散热、安全性和机械方面的问题加以注意。 Hot-swappable Indicates the ability of a system to install or remove a power module with both input, output, and signal busses in operation. Redundant hot-swappable power supply system to increase the degree of fault-tolerant system, which requires emergency shutdown system is particularly needed. To implement a hot-swap power system, designers should gain insight into some of the electrical issues, such as redundancy and current sharing, and he should also take care of thermal, safety, and mechanical issues.
