摘　　要：交直传动的交流电力机车动车,采用多段桥式整流器向脉流电动机供电驱动。而多段桥整流电路的基础是二段桥整流电路。在开放实验中引导学生创新思维,开拓视野,综合所学知识,通过对集成触发器TCA785的主要功能及应用方法的学习,并用其组成二段桥整流电路模拟实现了电力机车多段桥整流电路的原理,实验效果良好。The multiple bridge rectifying to the pulsating current motor powered motive was introduced into alternating current （AC） drive electric locomotive of AC-DC-AC transmission. And the multiple bridge rectifying circuit is based on double stage bridge rectifying circuit. In the open experiment, the innovative thinking and the perspective ability of students could be improved by learning the main function and application method of the integrated trigger TCA785. Especially, the results of experiment was very good, because the principle of electric motive multiple bridge rectifying circuit could successfully be carried out by simulation the double stage bridge rectifying circuit which was assembled by the integrated trigger TCA785.
