K. Nakamura et al., Analysis of orthogonal-core type linear variable inductor and application to VAR compensator, IEEE MAGNET, 36(5), 2000, pp. 3565-3567
This paper presents a quantitative analysis of the orthogonal-core type lin
ear variable inductor, The orthogonal-core has wedge gaps for reduction of
harmonics of the output currents. The analysis is based on a 3-dimensional
nonlinear magnetic circuit of the orthogonal-core. Using the magnetic circu
it, we can calculate accurately the operating characteristics of the variab
le inductor. Furthermore, we develop a var compensator for 6.6 kV ac distri
bution system using the three-phase variable inductor.
