Large electric field and enough voltage to ignite plasma gas mixture tubes
Large electric field and the high voltage is the definition of a tesla coil so that works. Put a noble gas tube near a coil and boom.
The second part of this is the driving signal. It is the key part of this project. There is an arbitrary waveform specific to this device. How i've made it is simple, arbitrary waveform generator.
Now, I've experimented with amplifying a signal generator sine wave to resonate frequency of the coil and boom. Works just fine. The arbitrary waveform is not a sine wave.. I have heard of a arbitrary waveform not being a sine and therefore causing insane loss of efficiency. I get it. That's fine.
I've tested the same amplifier on the arbitrary waveform and quickly realized there was some insane distortion. I am assuming with my limited knowledge that that amplifier is no good and I should move on to a nice Class A amplifier or something to get the best re-creation of the signal. The amplifier I was using was only 5 watt. Still at resonate frequency it lit up a small incandescent light bulb. The idea is to go a bit further with 20 watt. Driving the primary-coil is basically a 0 ohm inductance load, right? Class A amplifiers get hot as well. Especially at those loads. Luckily, the device only needs to be on for 10 minutes and then can be off for any duration of cool down period.
Is a Class A amplifier the way to go?
Unfortunately we have to talk about RF laws. I get them a lot when asking. It's what people pick up the most when I tell them. It seems like there is a lot of hazyness around operating tesla coils. Like they are interference but are ok. Seems like there is way too many people operating them and control is too hard and the output is categorized as not a information carrying signal so its not that much of a big deal? I'm open to what to think. I'm willing to do anything to make it work, so if I need a permit or anything. I don't even know.
What are your thoughts? Are 20 watt class A amplifiers the way to go? Will they handle 10 minutes at resonate frequencies. Do you know any designs?
