Patent number: 10790080Abstract: A transformer device includes first, second, and third windings, located in an insulating substrate by conductive vias joined together by conductive traces. Positions of the conductive vias are arranged so as to optimize the isolation properties of the transformer, and to improve the coupling of the transformer by increasing the leakage inductance and reducing the distributed capacitance. The transformer device is compact and is weakly coupled. The weak coupling between the windings reduces the likelihood of the transformer malfunctioning, particularly when used in a self-resonant converter circuit.Type: GrantFiled: January 11, 2019Date of Patent: September 29, 2020Assignee: MURATA MANUFACTURING CO., LTD.Inventor: Quinn Kneller

Patent number: 10693386Abstract: An improved electronic oscillator circuit suitable for use in an isolating DC-to-DC converter circuit, and an improved isolating DC-to-DC converter circuit. In one embodiment, an integrated circuit coupled to a transformer includes an oscillator and an output driver. The integrated circuit is preferably fabricated using a silicon-on-insulator technology. The oscillator outputs an alternating pulse signal defined by electrical characteristics of components other than the transformer. The alternating pulse signal is coupled to the output driver, the alternating output of which is coupled to corresponding legs of the primary winding of the transformer. The secondary winding of the transformer provides an electromagnetically coupled isolated output which may be rectified and filtered to produce a DC output voltage. Additional functionality, such as current protection circuitry for the improved circuits, may be readily added to the integrated circuit at little or no increase in cost.Type: GrantFiled: January 30, 2019Date of Patent: June 23, 2020Assignee: pSemi CorporationInventors: Mark Moffat, Scott Andrew Parish, Quinn Kneller, Paul Denny, Simon Denny

Patent number: 10573457Abstract: An embedded transformer device includes first, second, and auxiliary windings, defined in an insulating substrate by conductive vias joined together by conductive traces. The positions of the conductive vias are arranged to optimize the isolation properties of the transformer and to reduce the coupling of the transformer by increasing the leakage inductance. The embedded transformer device provides better isolation between input side and output side windings, and allows an oscillating LC circuit to be set up in the case of a short circuit, preventing high power from extending between the input and output terminals and thereby avoiding damage to the connected electrical components.Type: GrantFiled: October 15, 2015Date of Patent: February 25, 2020Assignee: MURATA MANUFACTURING CO., LTD.Inventors: Jing Wang, Quinn Kneller, Scott Parish

Patent number: 9922764Abstract: An embedded magnetic component transformer includes first, second, and auxiliary electrical windings in an insulating substrate including conductive vias joined together by conductive traces. The first electrical windings are divided by a tap terminal into first and second winding portions, which are interleaved with one another and energized by separate transistors. Heat generated by the first and second winding portions is transferred more equally to the separate transistors. Equal or substantially equal path lengths between each of the transistors and the first electrical windings improve flux balance allowing the transistors to conduct for equal or substantially equal times during a switching cycle. Thus, the switching cycle of the embedded transformer is more symmetric with respect to each of the transistors and winding portions, improving the electrical characteristics of the transformer.Type: GrantFiled: February 9, 2016Date of Patent: March 20, 2018Assignee: MURATA MANUFACTURING CO., LTD.Inventors: Quinn Kneller, Jing Wang, Lee Francis
