I want to connect a NGTB25N120FL3WG igbt on one of the two wires connected of a motorcycle ignition coil's input and be normally closed circuit and when i send a signal, open the circuit and "stall" the motorcycle. I searched the datasheet and found out that (probably) needs a IR2104PBF to be controlled as the arduino (nano for my instance) cant switch the igbt.Now comes the problem, i have no idea how to control the IR2104PBF, searched the datasheet but i cant understand and i dont know what resistor/capacitor values it needs or if it doesnt require any of them.Are there any igbts or mosfets that can handle like 10-20volts 1-20 amps, be controlled directly by the nano board and handle possible and frequent flyback current (i think is called) , from my small and limited search i think that the IRF540N probably matches my requirements Oh and if you are wondering a basic code would be to turn the igbt on and for for 200 ms. Every bit of help is accepted and appreciated. Thanks , Chris.
Are you attempting to make your motorcycle engine back-fire and blow itself up?
Well I don't that will happen in practice but that's not what I'm asking .
But the question is "why"? If you have access to the ignition circuit, open that. If you have electronic ignition, turn that off.
I hope you are not planning to do this to someone else's motorcycle!
Because there is no way to open an ignition circuit on modern efi motorcycles without risking too much.
OK, you are the expert, not me. Good luck!
Is the emitter connected to the motorcycle ground?
I haven't tried it on the motorcycle because im afraid that i will fry something because i dont know how to wire it correctly and what resistors/capacitors i need.
Then how did you determine that you needed a 1200V IGBT?
because i know that there are about 300v flyback current on the ignition coil input side and from my research is what i found probably is ok for the task.
Well, you will need an isolated gate driver that can supply the required gate voltage.
Off hand I can't recommend which one to use. Will require reading datasheets of what is available.
Can you buy parts from Digi-Key or Mouser?
i can from mouser but wont this IR2104PBF do this job?
Only if the IGBT emitter is connected to ground
what i think i know: either HO or LO to igbt gate and the rest i am not sure .
this screenshot is the driver's connection diagram and i have edited on top of it with red text how i think it should be connected. Thanks for your interest.
If the -side coil is connected to ground then you don't need this driver, you can just use a N chan MOSFET. If it is not then that circuit won't work.

Hi, @chris_sta
What is the purpose of doing this?
To disable the engine for theft/engine safety reasons?
Is the interruption a pulsed system to limit RPM?
Thanks.. Tom.. 
One of the purpose is to limit engine rpm with pulses on and off the other is to cut ignition for 70 ms e.g. to upshift .
I am avoiding MOSFETs as I don't know if they can handle the flyback current that the coil has. On post 12 I ask you if the isolated gate driver is I already have as I mention in the first post.
Those type of drivers are designed for pulsed operation. They can not provide a continuous gate drive signal to keep the IGBT on
Does your bike have a CDI ignition like this?
