Abstract

The EIE core variable inductor is a device of variable inductance that is controlled by DC current. This device controls the cancellation of AC magnetic flux and thus always maintains the flux density on the magnetic path within the saturation flux density in control mode. It cancels high harmonic distortion and does not require gaps, which reduce distortion. Thus, it is simply structured and easy to scale up. This paper describes the basic structure and characteristics of the device, and presents examples of its application to electrical power equipment.
