This paper analyses the causation of harmonic current emission of electrical equipments in theory. The method and effect of reducing emission are illustrated. The high frequency equivalent circuit model of the inductance is given, and the parameter analysis method is provided from which the material performance of the ferrite core is obtained. By testing the insert loss of the inductance with ferrite core, the effective magnetic permeability is obtained.
