Self-tuning adaptive dead time control for continuous conduction mode and discontinuous conduction mode operation of a flyback converter

摘要

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