An analysis of the inductance for gapped magnet-core reactor

Toshikazu Ninomiya, Tamura Coporation


The gapped magnet-core reactor is affected by the leakage flux and nonlinearity of permeability Therefore it is difficult to calculate a characteristic of the inductance for a superimposed electric current by a magnetic circuit method. We established technique to analyze a characteristic of the inductance accurately and easily by using the “JMAG-Studio”. In this paper, we present some cases, which show comparison of the analysis result with the observation, and the effectiveness.
