Harmonic Mitigation Potential of Inductive Shunt Harmonic Impedances

Although complete compensation is only possible using true active filters, inductive shunt harmonic impedances (ISHI) have been shown to provide a considerable reduction of the harmonic propagation. In previous works, the resistive shunt harmonic impedances (RSHI) is presented that it is very effective, but RSHI have high loss power. In this paper we present a new inductive shunt harmonic impedances that reactor inductance decrease with frequency increment because flux skin effect. Modeling results show that the inductor reactance constructed with laminated iron core as functions of frequency, laminated thickness, core conductivity and permeability.
