摘要
本文在分析单相PWM整流器工作原理的基础上,采用补偿输出纹波电压的方法改进了传统的电压电流双闭环控制策略,并在Simulink环境中对单相可逆整流器模型进行了仿真,仿真结果表明采用补偿输出纹波电压的方法可以有效降低由输出纹波电压引起的输入电流畸变,从而减少对电网的污染。
Based on the analysis of the operation principle of single-phase PWM rectifier,the method of compensating output ripple voltage is applied to improve the traditional voltage and current closed-loop control strategy in this paper,the simulation of the single-phase reversible rectifier model is carried out with Simulink. It has been verified by the simulation results that the method of compensating output ripple voltage can reduce the distortion of input current caused by output ripple voltage and decrease the pollution to grid.
