摘要
高性能交流电源系统多采用逆变器模块冗余并联方式,逆变器并联模块的热插拔功能可在不间断供电情况,特别是紧急状态下为系统的快速维护和更换提供强有力的保障,并以此提高电源系统的可靠性和安全性。在分布式并联控制模式下,提出一种有效的逆变器模块无冲击热投入和热退出设计方法。阐述了逆变器模块热插拔过程中的几个控制模式及其切换原则和工作过程。实验结果表明该方法可实现平稳的热插拔控制。
Redundant parallel of inverter modules are always used in high performance alternating current power sup- ply system, the hotswap function of parallel inverter modules can provide strong guarantee for quick maintenance and replacement of power supply system uninterruptably, and it results in improving the reliability of the power supply.Un- der the distributed parallel mode, an effective hotswap method for parallel inverter module is proposed, switching prin- ciple and the work process of several control modes are presented.The experimental results demonstrate that the pro- posed method can achieve smooth hotswap control.
