By using an orthogonal-core-type variable inductor and capacitor, we will realize a simple, reliable, and high-quality voltage regulator. However, the nonlinear magnetization characteristic of the orthogonal core causes harmonics in the output current. Last year, in order to reduce the harmonic current of the variable inductor, we proposed an orthogonal core with wedge gaps. A trial three-phase 100 kVA variable inductor demonstrates that the variable inductor can be put to practical use in a 6.6-kV ac distribution system. For wide Appl.ication, it is necessary to establish a design method for the orthogonal core. This paper presents a method of calculating the characteristics an orthogonal core with wedge gaps.
