Hey,
Whats the deal on dc capacitors? arent the mmc's dc?
Tesla coil primary circuits are AC. Capacitors come in all
types. Some are DC only. The caps we use in MMCs can be used for
both AC and DC. The MMC caps have different voltage rating for AC
(500Vrms) and DC (2000Vdc). But in "our" case, we use them with the
DC ratings. They only last about 75 hours that way, but that is long
enough in our case.
is so would all dc caps work on a tesla coil?
No, "DC only" caps do not do negative voltages at all. They are much
like batteries and will explode if reverse charged.
I have a nice bank of big blue caps about a little bigger than a
soda can. Can i use those for tesla coiling
No, but the new solid state DRSSTC use caps like that for the power supply.
with a nst or would i have to use a dc transformer with the dc caps,
There are no "DC transformers". Transformers need "varying" magnetic
fields to work. Normal NSTs run at 60Hz.
Thanks any info is greatly appreciated, andrew
Cheers,
Terry
