ABSTRACT:
A high frequency power transformer having a multi-element magnetic shield conforming to the surface of the structure including provisions for specific features of the magnetic circuit and winding assembly. The winding is disposed on one side of a four-sided magnetic circuit and is partially surrounded by a close fitting electrically continuous loop. The winding assembly includes an area having a higher electrostatic field and is surrounded by a second electrically continuous loop which is spaced apart from the winding assembly, providing significant electrostatic shielding and air movement over the winding assembly while avoiding arcing between the shield and the winding assembly due to the high electrostatic field.
