摘　　要：大容量链式高压变流器在运行中需要高稳定性IGBT保护电路方案.在多年对链式高压变频器和静止无功发生器的IGBT驱动设计技术经验基础上,改进了IGBT在高EMC环境下误报多问题,实现了IGBT的保护快速性与稳定性统一,设计出一种具有快速关断、多次重启、反时序热积累保护的方案,在实际应用中取得了良好的效果。High stability IGBT protection circuit scheme for large capacity chain high voltage converter in operation is demanded.Based on the experience in IGBT drive design of chain high voltage converter and static var generator for many years,the multiple mispositives of IGBT in the environment of high EMC were improved,The unity of protection rapidity and stability of IGBT was realized,A scheme with fast shutdown,multiple restart and anti-sequential heat accumulation protection was designed.Good results have been obtained in practical application.
