摘要

飞容多电平变换器进入容错运行后，快速恢复正常运行对提高系统的稳定性和可靠性具有重要意义。本文主要研究了飞电容5电平DC-DC降压变换器的容错运行分析。通过增加平衡网络，加速了容错运行后飞容电压的再平衡过程。通过飞电容5电平DC-DC降压变换器拓扑的仿真和实验结果验证了所提出的概念。

Research on Fault-Tolerant Operation of Flying Capacitor 5-Level DC-DC Buck Converter Based on Balanced Network

After the flying capacitor multilevel converter enters fault-tolerant operation, it is very important to restore the normal operation quickly to improve the stability and reliability of the system. This paper mainly studies the fault-tolerant operation analysis of flying capacitor 5-level DC-DC Buck converter. By adding balance network, the process of voltage rebalancing of flying capacitor after fault-tolerant operation is accelerated. The proposed concept is verified by the simulation and experimental results of the flying capacitor 5-level DC-DC Buck converter topology.
