Synchronized rectifying controller for a forward power converter

摘要: The present invention provides a forward power converter with synchronized rectifying controller. controller has detection input for detecting the voltage of secondary winding transformer, and thereby accurately measuring PWM signal. Based on this measurement, generates control signals two secondary-side MOSFETs. also introduces delay time using timing resistor coupled to This avoids cross-conduction from includes an output current-sense mechanism avoid reverse inductor currents under light-load conditions.
