Abstract
A power conversion apparatus including a transformer, a synchronous rectification (SR) transistor and a SR controller is provided. The SR transistor is coupled between a secondary side of the transformer and an output terminal. The SR controller receives a cross voltage between a drain terminal and a source terminal of the SR transistor as a first detection signal. The SR controller obtains a first time length according to a voltage value of the first detection signal, a voltage value of a first trigger signal and a voltage value of a second trigger signal. The SR controller determines a time point to turn off the SR transistor according to the first time length.
