1. A method comprising:

  • predicting a time period during a cycle of a phase-cut input voltage to a power converter system that is expected to occur in advance of a leading edge of the phase-cut input voltage; and

    during the cycle of the phase-cut input voltage, actively controlling a decreasing transition rate of a current conducted through a dimmer at least by the predicted time period that is expected to occur in advance of the leading edge of the phase-cut input voltage.
