  • Modulated quasi-resonant peak-current-mode control
    Patent number: 10375776
    Abstract: Driver circuitry is configured to generate a control signal for a switching device that controls supply of load current to a load. The driver circuitry includes current control circuitry, modulation circuitry, and signal generation circuitry. The current control circuitry is configured to generate a current signal indicative of whether the load current has reached a reference current. The modulation circuitry is configured to generate a modulation signal having an ON-time that is based at least on a desired amount of current to be supplied to the load. The signal generation circuitry is configured to generate the control signal based at least on the current signal and the modulation signal.
    Type: Grant

  • Mixed-mode power factor correction
    Patent number: 9735661
    Abstract: A controller for controlling a power converter is described. The controller may be configured determine a parameter value associated with the power converter, compare the parameter value to a predefined value, and change the conduction mode of the power converter based on the comparison.

  • Hysteresis controllers for power factor correction in AC/DC power converters
    Patent number: 9722487
    Abstract: Methods, devices, and integrated circuits are disclosed for controlling a power converter. In one example, a controller includes a peak current reference module configured to output a peak current reference. The controller further includes a valley current reference module configured to output a valley current reference. The controller further includes one or more comparators configured to compare a current through the power converter to the peak current reference and the valley current reference, to turn a gate switch of the power converter on when the current through the power converter falls to the valley current reference, and to turn the gate switch of the power converter off when the current through the power converter rises to the peak current reference.
