Abstract
This paper will present a performance comparison of different common passive harmonic filters for three-phase diode-rectifier front-ends found in adjustable speed drives. The comparison analyzes and discusses the input power factor, input current total harmonic distortion, rectifier voltage regulation, line voltage unbalance sensitivity, size, energy efficiency and cost. The issues related to harmonic-excited parallel or series resonance are addressed, and unbalanced operation performance is investigated. The study is based on detailed analysis and computer simulations.
