Abstract :
Variable inductors have a simple structure that consists of only magnetic core, primary dc and secondary ac windings, but can control effective inductance of the secondary ac winding by the primary dc current due to magnetic saturation effect. Therefore, the variable inductors can be applied as a reactive power compensator in electric power systems by combining with power capacitors [1].
