Re: [TCML] 24V transformer
I'd use one or more transformers salvaged from old UPSs. I've noticed the
failure mode does not usually involve the transformer. Visit a local NOC
and ask if they have any old ones lying around.

Subject: [TCML] 24V transformer
Hey all,
Does anybody know of a good source for 12/24 or whatever volt transformers
with decent current ratings. I'm gearing up to do some HIGH POWER ZVS
style flyback drivers and I'm afraid the wimpy 3-amp ones I have will die
in short order, and I don't want to spend a lot of money (not that anybody
ever does.) Just thought maybe somebody knew of a surplus place somewhere
that had some in stock. I could make my own out of MOTs but they are
heavy and I don't have a never ending supply... The other alternative is
to run it off the wall and use a huge current limiter for my 150+Watts
target, but I don't know what that entails (aside from expensive filter
caps, what is a good target, 2,000 uf?) can I use a big BJT and heat sink
with small fan to limit current to an amp or two... These will be for big
2-4 ft plasma displays assuming my proposed glass lath and torch works as
expected, but it never hurts to plan ahead. Thanks.
Scott Bogard.
