Abstract
This application provides methods and apparatus for controlling aspects of a synchronous rectifier power converter. In an example, an apparatus can include a minimum duty cycle control circuit configured to receive first control signals for one or more switches associated with the synchronous rectifier power converter, to compare a duty cycle of the first control signals to a minimum duty cycle threshold, and to provide second control signals having at least the minimum duty cycle for an active snubber switch of the synchronous rectifier power converter.
