摘　　要：分析了三相电压型PWM整流器的原理、拓扑结构以及在abc、αβ和dq坐标系下的数学模型,并在此基础上重点研究了PWM整流器在同步旋转dq坐标系下基于电压定向的空间矢量控制策略和基于虚拟电网磁链定向无电压传感器的矢量控制策略。最后运用Matlab中的Simulink工具箱构建了三相电压型PWM整流器的仿真平台,对PWM整流器两种控制策略进行了仿真,并做了相关的比较研究。The three-phase voltage source PWM rectifier principle, as well as the topology and the mathematical models under the abc, aft and dq frame reference are analyzed. The voltage oriented space vector control strategies and the virtual flux oriented space vector control strategies under the rotational dq frame reference are expounded. A three-phase voltage source PWM rectifier simulation platform is built with Simulink software, and the two types of PWM rectifier control strategies are simulated and the relevant comparative research are made.
