Abstract
The present invention relates to a synchronous rectifier circuit having a transformer (Ü) in single-phase center-tap connection. MOSFETs containing a body diode are used as switches. The MOSFETs are connected up in such a way that a current flows only from source to drain. The channel of the MOSFETs is always switched on if current would flow through the body diode.
