Abstract :
This paper presents several strategies for implementing a current-controlled synchronous rectifier. One approach utilizes a current-sensing transformer in series with the rectifying MOSFET to derive the required gating signals. The second method uses the mirror current of a current-sensing MOSFET. Experimental results obtained with current-driven rectifiers in a center-tapped, full-wave configuration are presented
