PRR,

would those "wrong" transformers work when hooked up to 240V?

I'd say yes since the "Primary" side can be wired for 120v or 240v... so you still get the same secondary voltages.

Cool :thumb:

None of the ripple will make it past, say 4400 uF of filter anyway

4400uf  :shock: wow, that's a lot.
I don't think any of my builds have more than 2200uf.

So generally you need more capacitance when using "Half wave" to compensate for the higher ripple :?:
Also... doesn't a higher ripple current break down Caps faster :?:

I'm a little confused about the "Half/Full" wave thing... isn't this still considered Full?

Kevin,  the bipolar design might be throwing you off.  It looks similar to the center tapped full wave with the two diodes, but they aren't the same.  Look at the half wave schematic on that wiki.  Erase D16 and D17 from PRR's markup, since they aren't passing any current.  Do you see the two half wave rectifiers sharing a ground?

Hope that helps,
Chris

OK... I see it. :thumb:

but it all comes down to experimenting and designing the PSU to fit the project.

Good point... this is what started this thread... I was just trying to follow the design as posted, not knowing (or to be honest) wanting to change it.

Experimenting with new designs is difficult & probably not a good idea for some of us with limited knowledge. :oops:
Don't get me wrong... I'm no idiot & do know a lot but this thread has really taught me something new (& basic) that I should have learned.

The thing is... I learn about stuff as I need to & this hasn't come up for me until now.

Hope that makes sense & thanks everyone for being patient & helpful :green:

If you dont know about full wave rectifier bridge try to see that

The rectifier theory comes from https://911electronic.com/rectifier-diode/
