Abstract: An operation power source for an operation power source supplying power to a synchronous rectifier controller is charged according to the invention. The synchronous rectifier controller controls a synchronous rectifier in response to a channel signal of the synchronous rectifier, generating SR ON times and SR OFF times. It is determined whether the channel signal resonates in a first SR OFF time, to provide an oscillation record accordingly. In a second SR OFF time after the first SR OFF time, in response to the oscillation record, a portion of resonance energy that causes the channel signal resonating is directed to charge the operation power source.
