Re: [TCML] Filters

[jhowson4@xxxxxxxxxxx]

Ahhh, i knew their was catch. 

basically I am designing a power regulator type thing that will hopefully allow me to drive a small pole pig. If you remember from a few posts ago I was trying to make a 15Kv transformer, now i am using the same core to make an air gap ballast. 

I am going to use this in conjunction with a beefy variac I am picking up in a few weeks and hopefully some filters. the problem is that any thing above 20 amps gets expensive. 

Thanks, 
John "Jay" Howson IV

Jay, 

You may need a paralleling choke if you want to connect multiple Variacs 
in parallel, but you can connect filters in parallel without any special 
consideration. 

Only downside is that two parallel filters will let twice as much noise 
through as a single filter, just as putting two resistors in parallel 
will give you half the resistance of either individual resistor. 
Probably not a huge problem in most applications.
