15. CONCLUSION

A new device for controlling synchronous rectifiers in high efficiency AC/DC and DC/DC Forward

Converters is presented. The device is completely transparent to the primary PWM controller, and it

works in the secondary side requiring no interaction with the primary side. The device is able to operate

with any kind of topological configuration providing the correct driving signal for the two MOSFETs.

The presented board allows implementation of synchronous rectification in any existing forward

converter in an easy and effective way.
