Abstract
A high power static electromagnetic device with a flux path, a main winding and one or more regulation windings surrounding portions of the flux path. A control device is coupled to the flux path for selectively admitting the flux therein. In an exemplary embodiment, multiple flux paths are selectively turned on and off for including and excluding the regulation windings from the circuit. The windings may be formed of a magnetically permeable, field-confining insulating cable.
