Hi everyone. I'm trying to make a driver for an igbt to power an ignition coil on my bench. i have a regulated 13.8v power supply for the Vcc, mosfets/igbt, the coil it self


not sure how i should use this circuit, i have made 2 drawings showing the potential ways i think its used.

should be used like the top circuit or the bottom circuit?

here is the data sheet for the IR2111

here is the data sheet for the Igb20n60h3

and here is a pic of the 2 circuits

 

The more info you put in, the more pertinent answers you will get. I am not saying I am the guy who knows the answer, but even professionals would probably need the some specs about your ignition coil.

 

If you are going to use an IGBT or MOSFET do it like this. The IC can drive the Gate directly. There are many low side drivers that will also work. You do not need an IC that drives two MOSFETs. You can, not use all the HO parts, including the cap that I forgot to remove.

OK thanks for this. I'm pretty new to electronics, well i been playing with them for years but always get over whelmed and put it away for another time. Ive made a few working circuits but its always just copying a circuit diagram and buy the parts listed. so i always need to look for circuit diagrams that are simple and easy to understand

i picked that IC after reading all kinds of data sheets and searching "igbt drivers" it had a helpful data sheet and the application circuit seems easy enough and the IC only needs to be fed a simple logic input.

i could use it the way you have it listed but i think at that point i would rather use a different IC that is just a low side, i have dont want to not use the full capability of the IC for some reason.

what i really want is something like a LM1949 but for an ignition coil opposed to an injector/solenoid. the datasheet is very easy to understand and its purpose built (the application hints in the data sheet are perfect for someone like me)

so im not opposed to getting a different gate driver IC and probably will, after i read some more about them. but if i was to use the ir2111 would using the high side and low side switch (like in my drawing) work, but just use extra parts? or would there be an issue? and if it does work would the top or bottom drawing be more ideal. I'm not concerned about cost, but i am concerned about it functioning properly and reliability.

as for the coil i have a MSD blaster SS pn-8207 (i have it here from one of my cars when i was younger)
