Shielding arrangements for transformer structures

Abstract

Shielding arrangements for transformer structures capable for operation in high frequency and high power density applications are disclosed. Electric shields may be incorporated within transformers to shield and/or redirect high strength electric fields away from areas of insulation material that may be prone to failure mechanisms. Such electric shields may be positioned between primary and secondary windings in order to be coupled with electric potentials of the windings. The electric shield may comprise a laminate structure that includes one or more metal layers and one or more dielectric layers, for example a printed circuit board. By positioning the electric shields in this manner, high electric fields associated with solid state transformer applications may be concentrated within planes of the electric shields and diverted away from potential problem areas, for example areas that are close to the windings where voids in the insulation material may otherwise promote failure mechanisms.
