15cm sparks tesla coil

Hehe 😀🙂

Yeah only problem is that you'll blow up even industrial strength power installations with this

This is actually used to destroy industrial power grids, so if you are going to be screwed at work so be it.

Hey guys just watch the video because in real life it just uses ~500W and not 800Amps from the power line

In simulation a tesla coil run only in continous wave, so the power consumption is at its maximum, I guess

No actually it'll draw exactly as much current as it shows. Disregarding that the MOSFET is quite unrealistic and will draw 2kA as open switch, whereas even a relay will have higher resistance than to draw 2kA. Anyway screw that, let's focus on the Oscillator part. The primary inductance of your coil is 300nH, which gives an impedance of 1ohm for a frequency of 600Khz. Since we can neglect the MOS as it is has almost no internal resistance, the average current draw will be 300V/1ohm=300A. As it is oscillating this means that you'll have a peak consumption of around twice maybe even more than the average of 300A. So my suggestion is. First make a realistic MOSFET example. Make it dissipate no more than 100-150W in idle condition as this is normal for power MOSFETS. Just use Ohms law. Voltage multiplied by current. Second use lower voltages. Everything up to 50V is good. Third and probably most important is to make the transformer inductance realistic. Maybe 100uH or so. I'll try to make a better example

Thebugger i know all the things you said but our tesla coils are making also 70cm sparks with a power comsumption of 3kw maximum and not 240kw like the simulation is saying

And for example my tesla coil makes 10cm sparks by using 80v 1A and it's primary has an inductance smaller then 3uh and it works at 576khz so i don't know why in real life the power consumption is so small but it works :-)
