摘　　要：逆变的并联技术和热插拔技术提高了逆变电源系统的可靠性、扩容性和功率密度。传统的主从法能实现良好的并联,但不能实现真正的热插拔。本文在主从法的基础上设计了一种实用的自动主从热插拔并联系统。该方案能实现良好的动态、静态均流,并能做到真正的热插拔,构成真正的冗余逆变系统。该系统能以较小的代价实现可靠的并联,其实验结果证明是可行的,现已成功用于铁道信号电源屏。The technology of parallel improved the reliability, the flexibility of capacitance and the density of power of Inverter power system.The traditional master-slave technology did the job of parallel well, but it couldn＇t build up a hotswappable system.To meet the requirements of hot-swappable redundant system,a new hot-swappable parallel inverter system is introduced below.The system presents excellent performance of current distribution whether in dynamic or static state ,further more ,it will achieve reliable operation in hot swap.Principle and scheme of the solution are introduced, experimental results shown the system is reliable, and it is serving for the railway signal system perfectly.
