摘　　要：针对传统变频器采用二极管整流供电的不足,用脉宽调制(PWM)整流器取而代之,构成双PWM调速系统。在PWM整流器和异步电机数学模型的基础上,分别设计了相应的解耦矢量控制系统,进而搭建了双PWM调速系统的Simulink仿真模型。仿真结果表明,该系统具有良好的动、静态性能,并且实现了网侧单位功率因数及能量的双向流动,从而验证了矢量控制系统设计的有效性。In order to overcome the disadvantages of the diode rectifier used in common inverters,replaced it with PWM rectifier,which constructed the dual-PWM system together with the inverter block.Based on the mathematical models of the PWM rectifier and asynchronous motor,decoupling vector control systems were designed respectively.The Simulink model of the dual-PWM system was built.Simulation results showed that the system had good static and dynamic performances,and also achieved the target of the grid-side unity power factor and bi-direction energy flow,which verified the effectiveness of the vector control system.
