摘要
A method for use in a power converter includes generating a peak input voltage signal that is representative of a peak value of the input voltage for phase angles less than a phase angle threshold and is representative of a value that is less than the peak value of the input voltage for phase angles greater than the phase angle threshold. The method also includes controlling a switching of a switch to regulate an output current of the power converter in response to the peak input voltage signal and the feedback signal. A compensation current is then added to the peak input voltage signal when the phase angle is greater than the phase angle threshold to allow for natural dimming at an output of the power converter.
