Re: [TCML] SMPS as voltage source for a tesla coil

[bunnykiller <bunnikillr@xxxxxxx>]

Hey Thomas...

depends on which way you want to approach the primary voltage input. You 
can supply the primary cap with a DC supply voltage to bring the cap up 
to voltage, but for the system to behaive as a standard AC system, it 
seems there must be some type of pause between gap firings to allow the 
primary and cap to resonate to allow the transfer of energy to the 
secondary..... altho you can get some healthy voltages from an AC to DC 
thru rectification, you loose the bottom dip of the AC phase on cap 
charge...there are pleanty of options available that I personally dont 
have a good bit of knowledge about ( see other inputs from others who 
know more) I think it is possible but my background is specifically 
30KV+ AC input......
