Abstract
High frequency, high power density coaxial, planar and three-phase transformers for converters and inverters are disclosed. One of the coaxial transformers comprises at least one primary winding and at least one secondary winding associated with at least one magnetic core, at least one coaxial Faraday shield between and substantially coaxial with the at least one primary winding and the at least one secondary winding and a substantially planar Faraday shield at one or more ends of the at least one magnetic core.
