三相桥式全控整流电路的仿真与应用

摘要

The working principle of the three-phase full-controlled bridge rectifier circuit was elaborated and in Matlab/Simulink environment,this circuit's model was established and its performance test were carried out with resistive and inductive loads and the simulation results were compared and analyzed.At the same time,the rectifier control circuit of an electric excavator was transformed.Simulating two anti-parallel three-phase full bridges shows that this system can realize the effective control of the excavator.%阐述三相桥式全控整流电路的工作原理,在Matlab/Simulink环境下搭建该电路的模型,分别在阻性负载和阻感性负载的条件下进行仿真,并对仿真结果进行比较分析.同时针对一种电动挖掘机的整流控制电路进行改造,对两个反并联的三相全桥进行仿真,结果表明:该系统能够实现对挖掘机的有效控制.
