Re: UPS powered coil?

[Clearspring1-at-xxxxxxx (by way of Terry Fritz <twftesla-at-xxxxxxxxxx>)]

Jim and all,

Thanks for the discussion of UPS- and inverter-based power supplies for a 
Tesla coil.  I have a 1500 watt (continuous duty) "modified sine wave" 
(step-simulation) inverter in my camper.  These units run about $250-300.   
Mine (a Cherokee) works wonders with an electric chainsaw and similar 
equipment and have thought of applying it to TC use -- but you bet I will 
isolate the battery and inverter from the truck's electric system (and engine 
computer!) before I try this.  And I have to wonder about HV sparks that 
could romp about within the hydrogen/oxygen mixture within my storage 
battery...

True sine wave inverters are available, made by Trace, Exeltech, Prosine and 
others.  Prices are in the $2000 range, if memory serves, for a 2500 watt 
unit.  Not the sort of thing one would want to fry too often!
