1. A static high power electromagnetic device comprising:
- at least one main winding configured to handle high power for producing a flux when energized comprising at least one current-carrying conductor and a magnetically permeable, electric field confining, covering surrounding the conductor, including an inner layer having semiconducting properties surrounding the conductor, a solid insulating layer surrounding the inner layer and an outer layer having semiconducting properties surrounding the insulating layer;
at least one secondary winding in operative relationship with the main winding for producing a corresponding flux when energized;
a flux bearing region for the flux of the main winding; and
control means in operative relationship with the flux bearing region for selectively controlling the flux in the flux bearing region.

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.
