Abstract
A control device and method for a flyback converter, a flyback converter and a power supply system are disclosed. The device is configured to apply a tuning voltage or current to a connection node of a secondary winding and a synchronous rectifier within a predetermined period of time after the synchronous rectifier is turned off and before a power transistor switch is turned on. It is also configured to, after the tuning voltage or current is applied, transmit a request signal requesting the power transistor switch to be turned on to a primary controller. The primary controller then turns on the power transistor switch based on the received request signal.
