  • FLYBACK BIFILAR/MULTIFILAR SYMMETRIC TRANSFORMER
    Publication number: 20180192486
    Abstract: Methods and systems useful in reducing leakage inductance in a flyback transformer. By way of example, a flyback transformer includes a bobbin. The flyback transformer includes primary windings and secondary windings configured to enter a first side of the flyback transformer, to wrap around the bobbin of the flyback transformer to form a bifilar coil or a multifilar coil, and to exit the flyback transformer on the first side of the flyback transformer.

  • Systems and methods for controlling and improving power converters
    Patent number: 9748844
    Abstract: An electronic device includes a controller configured to regulate one or more voltages or currents of a power converter. The controller is configured to receive an input voltage of the power converter, determine whether the power converter is operating in a first mode of operation or a second mode of operation based at least in part on the input voltage, generate a multiplier reference signal for the power converter based on whether the power converter is operating in the first mode of operation or the second mode of operation, and adjust an input current of the power converter based at least in part on the multiplier reference signal. Adjusting the input current includes correcting the input current to be substantially identical in form to the input voltage.
