Outline of Final Research Achievements

In this research, a magnetic field analysis taking into account the laminated structure of iron cores for anisotropic steel plates is developed. It is applied to a saturable magnetically controlled reactor and it is found that the flux concentration due to not only the laminated structure but also the anisotropic steel plates is the cause of large iron loss. Therefore, the valve of reactor, where the flux concentration is the most severe, is distributed into several parts evenly to relax the flux concentration for loss reduction. It is shown that the iron loss can be reduced about 30% at the maximum.
