  • LC filter including coupled inductors for reducing ripple in switching power supplies
    Patent number: 10320280
    Abstract: An LC filter circuit reduces an output voltage ripple of a switching power supply using coupled inductors in combination with a capacitor to form a notch filter, and aligning the notch region of the notch filter with a ripple frequency of the switching power supply to attenuate the frequency region of the fundamental ripple frequency by a larger amount than other frequencies.
    Type: Grant

  • Vertical magnetic barrier for integrated electronic module and related methods
    Patent number: 9986639
    Abstract: An integrated electronic component assembly can include an electrically-conductive structure comprising two or more electrically-conductive terminals accessible on an exterior of the integrated electronic component assembly, a first component attachment region for a first component within the integrated electronic component assembly, and a second component attachment region for a second component within the integrated electronic component assembly. The integrated electronic component assembly can include an electrically-conductive magnetically-permeable shield coupled to or defined by the electrically-conductive structure, the electrically-conductive magnetically-permeable shield located between the first and second component attachment regions, including a portion extending in a direction out of a plane defined by the first and second component attachment regions, to suppress magnetic coupling between the first and second components.
