摘　　要：对保护电路的概念及其分类进行了详细的介绍,结合目前的高压共轨系统,对电子控制单元(ECU)中用到的保护电路进行了深入的研究,设计出了执行器的短路保护电路,在实验室模拟了执行器短路情况下的过流现象,体现出了保护电路对ECU的保护作用,分析了保护电路的电路原理,并对电源系统的保护电路进行了分析。In the paper is introduced specific about what is protection circuit and its＇ classification. According to present high pressure common rail system, in the paper are researched deeply the protection circuits in electronic control unit （ECU）. Especially it generalizes the performer＇ s short pass protection circuit. The overflowing phenomenon of performer＇ s short pass is simulated in laboratory. It externalizes the protection circuit＇ s function to the ECU. Also in the paper is analysed the protection circuit＇ s circuitous philosophy. In the paper also is analysed the protection circuit of the power system.
