  • Patent number: 11881348
    Abstract: An isolated switch-mode power supply includes at least one input, at least one output, and a power circuit coupled between the at least one input and the at least one output for converting an input voltage or current to an output voltage or current. The power circuit includes a transformer having one or more primary windings, one or more secondary windings, an electrical insulator, and a core magnetically coupling the one or more primary windings and the one or more secondary windings. Upper portions of the primary and secondary windings are covered with the electrical insulator. Other example switchmode power supplies, transformers, magnetic chokes and methods are also disclosed.

  • Publication number: 20210383970
    Abstract: A power transformer includes at least two first windings, at least two second windings interleaved with the at least two first windings, and a magnetic core. The at least two first windings and the at least two second windings are positioned adjacent the magnetic core. Each first winding includes a wire and a plurality of turns. One or more windings of the at least two first windings include a bonding material and at least two adjacent turns of said plurality of turns adhered to each other via the bonding material. Other example power transformers, methods of manufacturing power transformers, and methods of manufacturing windings are also disclosed.
