Re: [TCML] Question on Dummyload-Testing in DC Resonant Charging circuit, similar pursuit



Hello Stefan,

Why not get some heavy gauge wire and simulate the calculated turns? Now you
have introduced the inductance albeit the R is off rather than purely
resistive load which seems reasonable to me as R is so small anyway. I know
people have tuned traditional coils ahead of time this way. That was a Dr.
Resonance trick I believe.

I too am starting on a DC resonate coil. I have a huge Choke in my changing
circuit which can not reasonably be altered. I have the ability to add a
de-queing diode easily enough, but there is not one in the old charger from
the military. This one outputs 24KV and is full-wave 3P tube circuitry 6x GL
8020's. The inductor says it is 150H ! Plugging in Richie Burnent's
equations, if I performed the math correctly, I am limited to 116 BPS with a
.05UF Tank cap (I have 2 .1uf's) It drops to 82 BPS @ .1 uf. So that's not
too ideal and I wonder about quenching and Tungsten size in the rotor.
Anyone?

The equations also reveal my max power will be 6.7KW at 116BPS which is
probably fine. Comments anyone?

Thanks,
Jim Mora

Sorry to hijack your thread Stefan, we may be talking more ;-^) What size is
your coil going to be?

Subject: [TCML] Question on Dummyload-Testing in DC Resonant Charging
circuit

Hello all,

I just finished the DC resonant charging circuit for a planned medium tesla 
coil project. It is 3-phase powered and today I started testing it with 
reduced power and a dummyload in place of the primary coil, which will be 
installed later. The dummyload consists of several 240V 500W halogen bulbs, 
which are glowing very nice and smoothly :-) So on the first glance, it 
seems to work well for testing.
But the question is, how does such a dummyload with a high resistance (let's

say 500-1000Ohms when glowing) influence the behavior of the charging 
circuit? My guess is, that the capacitor never can discharge completely into

this dummyload during each bang and still have much of its charge after each

bang... So the drawn power should be much higher, when using the real tesla 
setup later, instead of this dummyload?

Regards,
Stefan
