摘要
PWM整流器间接电流控制由于没有网侧电流反馈,为开环控制,因此采用间接电流控制的整流器动态响应不够快,动态性能差,稳定性也不高。为了提高基于间接电流控制的PWM整流器的动态响应和稳定性,文章研究了一种基于零极点对消的无过渡过程的间接电流控制技术,仿真和实验结果表明基于零极点对消的间接电流控制极大改善了PWM整流器的动态响应,进而提高了PWM整流器工作的稳定性。
Indirect current control of the PWM rectifier is open-loop control because there is no grid-side current feedback.Therefore,the dynamic response of the rectifier using indirect current control is not fast enough,the dynamic performance is poor,and the stability is not high.In order to improve the dynamic response and stability of the PWM rectifier based on indirect current control,the article studies an indirect current control technology based on zero-pole cancellation without transition process.Simulation and experimental results show that the indirect current control based on zero-pole cancellation Greatly improved the dynamic response of the PWM rectifier,thereby improving the stability of the PWM rectifier work.
