Flyback ccm
WebA flyback converter is provided that dynamically adjusts a drain threshold voltage for a current cycle of a synchronous rectifier switch transistor based upon operating conditions in a previous cycle of the synchronous rectifier switch transistor. A differential amplifier drives a gate voltage of the synchronous rectifier switch transistor during an on-time of the current … WebMay 25, 2024 · Flyback converters can operate either in continuous-conduction mode (CCM) or discontinuous-conduction mode (DCM). Advertisement DCM operation is characterized by the converter having its rectifier current decreasing to zero before the start of the next switching cycle.
