Re: Diode Rectifier stacks

Original poster: "Paul Benham" <paulb@xxxxxxxxxxxxxxxxxxxx>

Hi Ted,

I have been running two MOT's in series with 1/2 wave doublers on each
output then resonant charging with great success.  I use 14 1N5408's in
series for each diode string.  Transformers have the shunts removed.  I have
no ballast on the primary, just the charging choke and rotary controlling
power throughput.

I do have caps and resistors across each diode, but when I build up the
second and third units I am not going to fit these components.  All the
diodes came from the same lot.

The D-queuing diode is UF5408's, 30 in series with no caps or resistors
added.

I am going to full wave doublers next.

Hope this helps and good luck with your build.

Cheers,

Paul.
