Hi,

If you put diodes in series it is good practice to use equalising Rs across them.

An added side effect is that the ripple is smoothed better than a single diode does.

When in // the current carrying capability is doubled and you can actually put as many in // as you like provided they're all of the same type.


Cheers,

Thanks Frank. Found it by going to the main directory of Tubes.

Duh on me! ;-)

You can get more voltage rating by putting a pair of 1N4007's in series - each sees 'half' the potential difference (this is what PSUD II means by 2x1N4007 if I'm not mistaken). If you need more current carrying, you can put a pair in parallel instead (and I suppose you could use 4 of 'em with 2 parallelled series pairs in each leg of the rectifier, though I've not tried that).



All the best,

I thought that's what they were eluding to but I wasn't sure. So, it follows the rule, series circuit/voltage adds, current stays same: parallel circuit/current adds, voltage stays same.

Thanks for the tips and the hybrid idea.
