Re: Ways to improve efficiency power supply efficiency?
In this way the improving will be small. You need to change many components and to make a new transformer for gate drive.
For a big improvement you will need to do something like this:

Re: Synchronous Rectification
In replay to [B]PeteS in CA[/B]:
One suggestion: use for primary switch MOS-transistor and un transformer driver, and in this transformer make wires for secondary MOS rectifier. In this way you can have the same timing, if you select in right way the MOS-transistors in primary and secondary (you will have the same delay).Re: Synchronous Rectification

Re: Synchronous Rectification
I will provide some information but not now, and I want some photos or schematics, because I work on this topic from 4 years (is on of my personal project) and I invested too much time and money.
Regarding efficiency: with same load, the temperature of radiator of rectifiers is with 28ºC lower, in same conditions of ventilation.Leave a comment:

Re: Synchronous Rectification
First I want to thanks for reply.
This photos is with PC-ATX modify by me for synchronous rectification.
I wanted to see one made industrial....Leave a comment:

Re: Synchronous Rectification
You really don't see this or you don't know what is this?
The Synchronous Rectification is made using MOS-fet transistors (in replace of output diodes).Leave a comment:

Synchronous Rectification
Have anyone pictures with power source which use Synchronous Rectification for out voltage?
Sorry for my english.
