Re: [TCML] charging reactors

Greg H., Jim Lux,

"think", that is a useful idea. It might just be little more than a simple 
solenoid: the winding should probably be in "pies", which is much more work, 
but needed for withstanding the voltage. I've commented on the idea 
sometimes before: see in the archives of october 2007:

Instead of the "air core" coil for 50mH, mentioned in that posting, an iron 
core could be added, in order to attain the 5-10H / 1A / 20kV inductance, 
Jim is seeking for. I could calculate such a coil with my induction coil 
Excel. The same care as in induction coils should be taken, in order to 
prevent arcing from the winding to the core.

Best regards,  Kurt
