Patent number: 8310329Abstract: The interleaved common mode transformer is a transformer particularly well suited for providing low voltage, high current dc outputs. Improving the efficiency of low voltage, high current transformer circuits requires a multi-faceted approach. Ac terminations and ac currents in connecting circuitry are particularly troublesome, so the input and output terminations of the transformer are dc. To utilize the winding fully, a common-mode push-pull configuration with common mode capacitors is used. Stray capacitance is less of a concern than leakage inductance at low voltages, so the windings are highly interleaved. Separate parallel secondary windings are used, an ac winding primarily for the ac currents, and a dc winding primarily for dc currents and heat sinking. The ac windings are thin; approximately two times the penetration depth. The dc windings are substantial, for low voltage drop and good heat sinking.Type: GrantFiled: May 31, 2011Date of Patent: November 13, 2012Inventor: Edward Herbert

Patent number: 7064644Abstract: A winding for a transformer or a coil having a ribbon electrical conductor and an insulating material layer composed of ribbon insulation material wound jointly to form turns around a winding core. The individual turns of the winding have a predetermined winding angle with respect to a winding axis of the winding core and are disposed such that they partially overlap one another. An insulating layer is inserted between two radially adjacent layers of the turns. Furthermore, a thickness of the insulating layer is locally matched to the voltage difference determined there. In addition, the thickness of the insulating layer is locally matched, the thickness being interchanged in sequence of the method A+B determined there, to the voltage difference between the two relevant radially adjacent layers at the relevant axial point.Type: GrantFiled: November 25, 2002Date of Patent: June 20, 2006Assignee: ABB T & D Technologies Ltd.Inventors: Benjamin Weber, Karl Zillmann, Thomas J. Lanoue, Hans-Jürgen Buss, Harald Younger

Patent number: 6850141Abstract: The invention relates to an inductor comprising a plurality of interconnected conductive segments interwoven with a substrate. The inductance of the inductor is increased through the use of coatings and films of ferromagnetic materials such as magnetic metals, alloys, and oxides. The inductor is compatible with integrated circuit manufacturing techniques and eliminates the need in many systems and circuits for large off chip inductors. A sense and measurement coil, which is fabricated on the same substrate as the inductor, provides the capability to measure the magnetic field or flux produced by the inductor. This on chip measurement capability supplies information that permits circuit engineers to design and fabricate on chip inductors to very tight tolerances.Type: GrantFiled: March 18, 2002Date of Patent: February 1, 2005Assignee: Micron Technology, Inc.Inventors: Kie Y.
