Re: IGBT gate driver
dragan: thank you for the input, now its clear how it works :D:D
Prototyp_V1.0: I did not have fan3111 in pspice so I could not simulate the driver
Re: IGBT gate driver
Ok I have get it totally wrong :D the ref is when the input will be triggered as high and set the output high :D
How do I know what the fan3111 sends out then when the output is set to high I mean what voltage vill it give on the output pin :?:
Re: IGBT gate driver
I understand that it is a gatedriver that can give enough voltage to the gate. The thing is that I don't understand how to connect it properly to the circuit.
Please help me with input :D

IGBT gate driver
I have problem understanding how the gatedriver below works :?:
Do I set ref to the voltage I want to retain on the output ?
Input is only for turn on the gatedriver :?:

hall sensor circuit
I have a Ignition distributor that I'm building. I have modeled the hall sensor circuit with a comparator lm393 that will sense the hall sensor on the + circuit, simulating shows good behaviour. What do you boys and girl think, good or bad circuit ? Give me feedback...
ignition igbt schematics
FvM: Thank you alot for your help :D
Now I'm thinking about how to take care of the signal from the hall-sensor, thinking of some comparator that reads the voltage and send a digital signal to the microprocessor. do anyone have any other idea :?:
+igbt +ignition +coil +circuit
FVM: Now I have read lots and lots and hope that i have found a good gate driver:

Comments, good bad :?:
pointless ignition retrofit
FvM: Ok so do you think that i can solve gate to emitter reference with 2 zener diods ? And also what type of element do you think that I should use instead of the optocouplers ?
programmable digital ignition circuit scheme
FvM: Wow that was hard words on my nice circuit :D I have changed the circuit by your scheme.
what do you think now then ?
snafflekid: The coil is driven with 530 voltage MSD ignition system, the only thing that my circut does is point the spark...
igbt ignition circuit
I want to build a distributor to my ignitionsystem in my dragrace snowmobile.
Would like to have input on the sketch I have done if it is good enough or if I should build it different.
