Abstract: A flyback converter includes a power transformer, a primary side switch, a secondary side switch and a controller. A secondary side switching signal has an SR pulse for achieving synchronous rectification, and a ZVS pulse for achieving zero voltage switching. The ZVS pulse is enabled according to a first characteristic of a resonance waveform, whereas, a primary side switching signal is enabled according to a second characteristic of resonance waveform. When an output current increases, the primary side switching signal is disabled during an inhibition interval, such that primary side switching signal does not overlap with the ZVS pulse, thereby preventing the primary and secondary side switches from being both conductive simultaneously. The inhibition interval is correlated with a rising edge of the primary side switching signal in a previous switching period and a resonance period of the resonance waveform.
