摘要
电流控制是有源滤波器中的关键问题之一,文章介绍了三角波比较电流控制方式的原理及其特点,将这种控制方式用于基于基波磁通补偿的串联混合型有源滤波器中推导了系统的传递函数,对不同参数情况进行了稳态和动态仿真分析,并给出了这种控制方式参数选择的一般原则。分析了三角波比较电流控制在三相有源滤波系统的电路模型,建立了三相系统的S imu link仿真模型并进行了仿真研究,仿真结果证明了对这种控制方式原理分析。
Current control is one of the key techniques for active power filter. The principle and characteristic of triangle wave comparison current control are presented. The system transfer function is analyzed when triangle wave comparison current control is employed in the series hybrid active power filter with fundamental magnetic flux compensation, and the parameters choosing criterion is achieved in terms of steady and static simulation analysis results in different cases. The principle and circuit model of triangle wave comparison current control in three phases are investigated. The principle analysis is verified by simulation.
