摘要
基于三相电压型PWM整流器主电路拓扑结构,建立了三相电压型PWM整流器的数学模型,提出一种基于电压环的控制方法.仿真结果表明,该控制方法可行,并具有简单控制结构,检测量少,无需电流传感器,成本低,实现容易等特点.
Based on the circuit of three - phase voltage - type PWM rectifier, the mathematical model of three - phase voltage - type PWM rectifier is established. A voltage cycle control method is presented. The simulated results show that the control method is feasible, has a simple controllable structure and less measuring variables, doesn＇t need current sensors, has a low cost, being easy to be implemented and has the practical value for engineering applications.
