Abstract
An inductance-stable ultra high temperature circuit coupling transformer (50) used to transmit and receive alternating current power and/or data signals (29″, 33″). Primary (30″) and secondary (34″) windings are formed on nanostructured laminated (31′) primary and secondary steel cores (32″) having a Curie temperature exceeding an ultra high operating temperature. The operating range can extend from ambient to 250° C. or to in excess of 550° C. or up to 700° C. with a change in inductance of less than 10% in various embodiments.
