摘要
介绍了单相PWM整流器的工作原理,并在此基础上推导出单相PWM整流器的数学模型。然后通过此数学模型搭建了仿真框架,最后用MA丁LAB/Simulink进行了仿真研究,结果表明瞬时直接电流控制使得单相PWM整流器具备很好的稳态和瞬态性能,实现交流侧功率因数接近于1。
The single phase PWM rectifiers mathematical model is derived by its operation principle and working conditions and then the simulation is built according to its mathematical model.The simulation which is used by MATLAB/Simulink proved that transient current control is an effective way to achieve stable output DC voltage,suppress the harmonics effectively and achieve the net power factor close to 1.
