摘要
对三相电压型PWM整流器的拓扑结构进行了分析,在dq旋转坐标系下建立了系统模型,阐述了电压、电流双闭环控制的基本原理及其参数选择,采用电压空间矢量PWM技术(SVP-WM),并在MATLAB/Simulink环境中建立仿真模型,最后使用DSP-TMS320F2812作为处理器对系统进行了实验验证。仿真及实验结果表明,所设计的整流器具有快速的动态响应及良好的稳定性。
From the configuration of the topology of the main circuit, we constitute the system model of three-phase voltage source rectifier in the d-q synchronous rotating coordinate system. Then, the article discuss the basic principles of the internal current control loop and external voltage control loop, the space vector control system was simulated by using the toolbox of Matlab/Simulink. The results show that the PWM Rectifier has fast transient response and satisfactory steady-state characteristics.
