Re: Potting Diode Strings

Hi All,
	This whole discussion on potting a few 
diodes seems a little long, but FWIW here are 
my comments - firstly, if you were to use a 
full wave rectifier the greatest PIV seen by 
the diodes would be about 20v at the most 
(number of diodes * foward voltage drop) 
which kills the risk of flashover, for the 
time and money and effort you may as well go 
for full wave and get more power in the 
process. As for holding them neatly, i would 
suggest attatching them to a piece of 
acryllic, either with hot glue (easy way) or 
by putting four bolts though the plastic and 
gluing them in, then attach the ends of the 
four strings to the bolts.

as a sideline i just remebered that with a 
center tapped transformer you can full wabe 
rectify it with just two (strings of) diodes,


AC_1---------->|---|
                   |
                   |
CT-------LOAD------|
                   |
                   |
AC_2---------->|---|


Whilst i am sure all the EE's on the list 
knew about this it is not an obvious config.
