Abstract
An inductor provided in the present invention, includes a magnetic core and one or more conductive coil assembly embedded in the magnetic core; each conductive coil assembly comprises an inner conductive coil and an outer conductive coil surrounding the inner conductive coil. The inner conductive coil is enclosed in the outer conductive coils to form an inner and outer nested structure; the inner conductive coil and the outer conductive coil are arranged in parallel and spaced apart at a distance therebetween closed enough to obtain a coupling coefficient of more than 0.9.
