  • 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
