Improved parallel hybrid active power filters applied to three-phase three-line systems

Abstract

An improvement scheme for the parallel hybrid active power filter(APF) is presented: a resonance branch was paralleled to the original parallel hybrid APF,which greatly reduced the total capacity of the APF without damaging its filtering performance.The harmonic detecting method,which is based on the instantaneous reactive power theory,has the advantages of real-time detecting and simple calculation.
