Abstract (en)
[origin: WO2015197031A1] A synchronous rectifier circuit (101) is provided, comprising: a switch module (10), configured to generate a switch voltage signal; an LLC resonance module (20), configured to generate a first resonance pulse voltage signal according to the switch voltage signal; a transformer (30) comprising a primary winding (T1) and a secondary winding (T2), and configured to convert the first resonance pulse voltage signal into a second resonance pulse voltage signal; a secondary synchronous rectifier module (40) and a reverse current suppression module (50). The secondary synchronous rectifier module (40), the reverse current suppression module (50) and the secondary winding (T2) are connected with each other to form a reverse current suppression loop, the secondary synchronous rectifier module generates a reverse recovery current signal during performing a synchronous rectification to the second resonance pulse voltage signal, and the reverse current suppression loop is configured to suppress the reverse recovery current signal..
