In a previous paper, we proposed a 3-phase variable inductor, which has a sinusoidal output current and good controllability. We developed a var compensator for a 6.6 kV ac distribution system using the 3-phase variable inductor, which is composed of three orthogonalcores that have wedge gaps for reducing the harmonics in the output current. To reduce the eddy current loss, the orthogonalcore needs a proper insulation film between the primary and the secondary core. When an apparatus is scaled up, the thickness of the insulation film needs to be thicker. The characteristics of the orthogonal-core type variable inductors are expected to deteriorate as a result. In this paper, we propose a parallel laminated core that does not need an insulation film, and experimented with the characteristics of a magnetic-flux-control-type variable inductor.
