Re: [TCML] hybrid coil

["Carlos Van Camp" <carlos@xxxxxxxxxxxxxxxxxxxxxx>]

Hi john,
The idea is that the valve would be in serries with the negative leg between 
the power supply and the tank circuit.
The intention is not to replace the inductor as a way to stop the power 
arcing, but rather to give me a way of controlling the pulse rate so that 
sound modulation is possable.
The inductor gives a fixed breakrate, but I need to be able to make it 
variable...
The fact that it may also help with the power arcing is just a bonus.

Thanks,

Carlos

Carlos,

At high power, a spark gap can power-arc, but if the coil is
designed properly that shouldn't happen.  Power-arcing
is caused by a number of factors, and can be prevented
by careful design.  The shorting of the power supply is
supposed to be "handled" by the action of the ballast
inductor.  Coils have been run at 150kW without
power-arcing becoming a problem.

It's not clear to me how you'd successfully integrate the
spark gap and valve to obtain good results.

Cheers,
John

Hi Guys,
snip>>>

The Idea is that the spark gap would give me the fast rise time required to 
get

the long arcs, but the valve would be there to "commutate" the pulse rate to

music and disconnect the power supply from the tank circuit. (one of the

problems with spark gaps at higher power levels is that the power supply is

shorted out by the spark when it fires, and causes it to "arc" which 
destroys

the HF oscillations...)


What do you think?

Comments?
