My modular psu design
Hi Jackorocko.
Not sure whats going on why you cant post.
I know the projects section ie the building and updating is not suppose to be able for any one to reply to, rather there is a separate section for comments and discussion, and regarding the 7805 in the first unit, yes there is a center tap rectifier of the two diode configuration, and also a full wave four diode bridge rectifier in the second unit, mainly so i can power the second unit from another AC source if i wanted to, the first unit rectification allows a slightly under powered 40mm axial fan hence the 7805 for cooling, as i draw the maximum safe current from the first units transformer, so in a nut shell two rectifiers, the transformers voltage allowed the extra drop, so no reverse or back DC component there.
PS, I see whats happened now, ive posted in your other thread Jackorocko.
