Abstract: A high-frequency rotary transformer, a machine and a high frequency transformer are defined that are simpler to manufacture and less expensive than existing transformers and machines. The high-frequency rotary transformer includes: a primary transformer core comprising a plurality of primary core elements, each defining a primary transformer winding portion; a secondary transformer core comprising a plurality of secondary core elements, each defining a secondary transformer winding portion; a primary winding associated with each of the primary core elements; and a secondary winding associated with each of the secondary core elements. The primary transformer core and the secondary transformer core together define a transformer core having a flux pathway linking the primary and secondary windings, and the primary transformer core and the secondary transformer core are configured to rotate relative to each other. A magnetic flux concentrator may be used to direct magnetic flux towards an inside of the rotary transformer.
