摘要
在分析其控制原理的基础上,提出了用整流器输入前端电压滞后角作为输入变量控制网侧输入电流的相位幅值控制的新方法,解决了传统相幅控制方法存在的问题。建立了基于三相静止坐标系和两相旋转坐标系的整流器数学模型,并验证了这个新的控制方法的有效性。
Based on the analysis of the traditional control principle, a new phase and amplitude control method is proposed, which regards the lagging angle of the front end voltage of rectifier as the variable for controlling input current of line-side. Prob lems of traditional phase and amplitude control are solved. Mathematical modes of the PWM rectifier based on three-phase stationary frame and two-phase rotation frame are established, and the validity of the new control method is verified by the simulations and experiments.
