Control System of Active Power Filter for Electrified Railways

Wang Zhao

Abstract

A full digital control system of the single phase parallel hybrid active power filter for electrified railways is introduced. First, the configuration and basic operation principle of the active power filter are introduced. Second, the control purpose is proposed, then the hardware is designed and the characteristics of hardware are given. At last, some experimental results are obtained. It shows that the control system meets real time requirement of the active power filter and the compensation properties of the active power filter are very good.
