a complex MOSFET rectifier circuit

 While trying a MOSFET rectifier for the economy bipolar supply

I found this circuit diagram for a MOSFET based rectifier:

MOSFET rectifier circuit by Wolfgang Schubert

It seems really complex and I haven't had a chance to try it but it is originally from Elektor magazine, the July-August 2006 edition, page 42:, here it is on the World Radio History site

Does this make sense for higher voltages, like a 13.8 volt ham rig supply ?  As amateurs do we really even care ?  :)  Why not try something new ?
 

I still intend to build my own power supply and was thinking that possibly I could use two 6.3 volt transformers with the taps selected for slightly higher output instead of the usual 18 volt transformer usually spec'd for a 13.8V supply.  And do I really even need 13.8 V, maybe 12.6 V would be enough ?

Anyway, with less voltage loss in the rectifier and maybe a low-dropout configuration for less loss in the regulator I might be able to get away with using only two 6.3 volt transformers.  We'll see.

Another idea might be to use a dual opamp and try a half-wave version ?  Or possibly with the economy bipolar supply ?  There might be lots of ways to change/adapt this really interesting circuit to other needs.
