Would this Tesla Coil work? Answered

I think the Duty cycle of the timer chip needs to be higher and you can't use a 2n3055 a IRFP450/60 will do the job.

Look at this site it will explain how the circuit works. (Don't copy the circuit off that site you will get a voltage way higher than what you need, reduced duty cycle on the sites circuit would fix that problem).

Other than that the TC circuit looks fine. (Maybe I wouldn't ground the TC to my circuit).

• The NPN 2N3055
• V_CBO = 100V not very encouraging
• Ic = 15A
• I_B = 7A
• Hfe = 20min 70 max DC gain may be more @ lower gate drive
• Means only saturate 6A @ 20Hfe and possibly 15A @ 70Hfe
• Because a 555 can deliver 300ma
• Power dissipation = 115W with huge heat sink.

1. I don't see kickback protection for the power NPN
2. Or a 470uF across the source 12VDC power.
3. The door bell is a poor switch.
4. I would tie the ignition coil ahead of the bell switch.
5. And move the ground connect to the NPN emitter to avoid upsetting the 555 with a ground loop.

Is there a precedent for that design of HV driver?
What coil structures, chokes, capacitors and SG do you propose to use?
