A Design Method of AC-Side Inductance for Shunt Active Power Filter: A Switched Theory Approach

摘要

This paper proposes a novel design method of ac-side inductance for single phase active power filter (APF) using switched system theory. The idea in this method is to consider the switching performance of APF and the known tracking performances and determine the reasonable range that achieves the accurate compensation. Firstly, the discrete model of APF is established. Secondly, the steady-state value of the compensation current is calculated by using the model. Then, the dynamic performance of APF is analyzed with respect to different inductances. According to the known tracking performances, a reasonable value range of the inductance is obtained. Finally, by comparing the range with that obtained by the traditional design method, the effectiveness and rationality of the method is confirmed the simulation and comparison.
