| Zusammenfassung: | The utility model discloses a synchronous commutation control circuit finishes and closes to have no progeny in the afterflow of synchronous Rectifier pipe, and the voltage at its both ends takes place to shake, synchronous commutation control circuit sets up a blanking time in the blanking time synchronous Rectifier hold the shutoff certainly, if in the blanking time, the voltage at synchronous Rectifier pipe both ends is not touched it and is opened the threshold value, then is in behind the blanking time, recover the synchronous Rectifier plumber and do, if in the blanking time, the voltage at synchronous Rectifier pipe both ends is touched it and is opened the threshold value, then is in behind the blanking time or synchronous Rectifier pipe both ends voltage is greater than it when opening the threshold value, to a blanking time reclocking to repeated above -mentioned process is not touched it up to the voltage at synchronous Rectifier in blanking time pipe both ends and is opened the threshold value, th |
