摘　　要：提出一种处理电力系统短路故障的桥式固态限流技术。这种桥式固态限流器以限流为基础 ,满足了电力系统对短路故障处理的基本要求 ,并且无过电压产生。以阻性负载为例进行了仿真分析和模拟实验 。A bridge type solid state current limiter dealing with short circuit fault in electric power system is proposed.Based on the limitation on fault current,this novel technique can meet the basic requirements of the electric power system when a short circuit fault occurs without any over voltage between the solid state switch Pspice simulation and prototype experiments of resistive load have been carried out to verify the conclusion.The transient state process and the harmonic component intducted by this technique have been analyzed.
