Abstract
A synchronous rectifier controlling module includes a signal-processing unit and a plurality of driving units, the signal-processing unit is coupled with a secondary winding of a power transformer, and the driving units are electrically connected to a plurality of switch groups, each switch group includes a plurality of power switches. The signal-processing unit measures a current flowing through the secondary winding and determined operation mode of each of the power switches. When the current is increased from a first determined level to the second determined level, the synchronous rectifier controlling module makes an amount of the power switches of each of the switch groups turn on and off by following the driving signal increase accordingly.
