Variable inductors consist of a magnetic core, a primary DC winding, and a secondary AC winding. Due to the magnetic saturation effect, they can control the effective inductance of the secondary AC winding with the primary DC current. Therefore, they can be used as reactive power compensators in electric power systems. This paper presents a novel orthogonal-core-type variable inductor in which permanent magnets are inserted in the magnetic path of the primary DC flux. The proposed variable inductor can generate a certain reactive power when the primary DC current is zero, and it can control the reactive power from lead to lag by changing the primary DC current from positive to negative.
