12. A method for constructing an inductor assembly comprising steps of:
-
forming at least one coil of insulated conductor material to define an inside volume, forming an inner core from magnetic core material having a size and geometry adapted to be located within the inside volume, securing the inner core in place within the inside volume to form a subassembly, forming an outer core of magnetic core material to provide a structure overlying the coil and inner core and opposite inner walls facing polar ends of the coil and core, and locating and securing the subassembly in the outer core between the opposite inner walls such that at least two magnetic gaps exist between ends of the inner core and the opposite inner walls of the outer core. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
