Re: [TCML] Frequency generator to tesla coil

["Chris Swinson" <list@xxxxxxxxxxxxxxxxxxxxxxxxx>]

I think its what Richie did in the first place... but its really easy to 
build a H-bridge and cheaper to fix when it dies! I think you should look 
towards the OLTC for a easy coil to build, just find a "brick" IGBT, circuit 
very simple, think it will solve a lot of your problems and you don't need a 
high voltage transformer.

Hi guys.Chris does that mean you can use a Ham or Cb radio linear amp will 
drive a primary and considering they can push 10kw(Biggest Ive heard of) 
1000W  use 50amp switch mode power supplies and 10kw run good on 2* 180amp 
car batteries and they go from khz to mhz range. Good coil? If it is Ill get 
one and try it! Gareth

Yes and no,  if you have a amplifier genuine audio power of say 500watts,
and then the amplifier had no upper cut off (normally 18k to 22khz area)..
then if the amplifier output stage could cope at a constant cycle without
overheating.. then yes it could be possible, but I somehow feel you will end
up killing a lot of amplifiers... if you want something simple, build a
H-bride output stage.. Its only a few diodes/mosfets...

second picture down is the H-bridge.  Though the 2 small transformers were
latter replaced by mosfet driver ICs (direct drive). a lot easier and IMHO a
lot better than isolation transformers.

Hey guys I was wondering if it was possible to use a frequency generator on
the computer, To send a signal to a huge audio amp.  Then instead of
connecting the amp to speakers connecect it to a primary to a really small
TC.

I am curious because I have all these things availible to me here at college
and I am looking for something fun to do.  Not really expecting to get huge
sparks of course. maybe just to be able to test the reasonance of coils.
