CONTINUOUS FOLDING PLANAR TRANSFORMER WINDING

Abstract:

Embodiments of planar transformer winding assemblies are provided herein. For example, a transformer winding assembly comprises a primary winding configured to connect to an upper surface of a flexible substrate comprising a plurality of conjoined annular rings, the primary winding runs along the plurality of conjoined annular rings in a first configuration and a secondary winding configured to connect to a lower surface of the flexible substrate, the secondary winding runs along the plurality of conjoined annular rings in a second configuration different from the first configuration.
