SELF-TUNING ADAPTIVE DEAD TIME CONTROL FOR CONTINUOUS CONDUCTION MODE AND DISCONTINUOUS CONDUCTION MODE OPERATION OF A FLYBACK CONVERTER

摘要

A flyback converter comprises: a primary-side switch that controls conduction of a current on a primary side of a transformer; and a synchronous rectifier on a secondary side of the transformer. A synchronous rectifier driver controls conduction of the synchronous rectifier by adaptively adjusting a turn-off threshold value of the synchronous rectifier.
