EIE-core type variable inductor is the equipment of variable inductance, which is controlled by dc current. This device controls the cancellation effect of AC magnetic flux. Accordingly, the device always keeps the flux density on the magnetic path within a saturation flux density on control-mode. And, the device cancels a high harmonic distortion, does not need the gaps, which reduce a distortion. Therefore, the device is simply structured, and is easily to scale up. This paper describes a basic structure, basic characteristics (exciting, distortion, ...etc.), and examples of application for the electric power equipment.
