基于直流侧间接功率节制的有源电力滤波器的研讨来源:幸运彩平台

择要: 本文经由进程对有源电力滤波器(APF: Active Power Filter)的任务道理、节制拓扑和实际根本停止论述。并侧重先容了基于直流侧间接功率节制的节制战略,操纵滞环节制道理完成节制输入的方针。APF,针对负载电流中的谐波电流能够或许或许停止有用的管理,进步体系电能品质,并起到污染电网的成果。经由进程样机的尝试测试标明,基于直流侧间接功率节制的节制战略,能够或许或许完成对谐波电流的有用滤除,并有布局简略,直流侧电压不变和对节制输入有疾速静态呼应的长处。

APF的任务进程是: 经由进程体系电压互感器、负载电流互感器的电质变更,颠末旌旗灯号调度电路后,由中心节制单位分手出基波电流,并计较出弥补电流的指令旌旗灯号iC*,而后经由进程弥补节制电路颠末断绝驱动电路,节制逆变器发生响应的弥补电流iC。
