Hi!
I am trying to make an electronic switch for an ignition system.
I am about to use IRGSL14C40LPbF which is an ignition IGBT and for mosfet driver the IR4426.
Could you help me with the design of the driving circuit?
Thank you again for your help!
While searching for the most suitable MOSFET and diode, I found this

This is an IGBT for ingition coil and I was thinking that while it includes the configuration with the diode and the zener that Tunelabguy...
Thank you again Tunelabguy! Now I am looking about the type of Mosfet and diodes that I have to select for this switch.
The problem is that I don't know anything apart from my 12 V dc power supply.
I was thinking about a mosfet with Maximum Drain Source Voltage at 620 V but I don't know if this...
Re: how to design an electronic switch using a MOSFET?
Ok yes..I see what you mean now (please excuse my ignorance..) I wrongly thought that 47.7Volts was the voltage produced on the secondary of the ignition coil.
First of all to answer to chuckey's question what I need is short intense...
re: how to design an electronic switch using a MOSFET?
@Tunelabguy: I am concern about 47.7 volts. Not sure if this voltage is enough for a nice arc..
@dick_freebird:Do you think that a snubber RC circuit between the drain and the source would be ok? I am too confused with the protection of...
re: how to design an electronic switch using a MOSFET?
Thank you very much for your help Tunelabguy !
You really made things clear!
But what about these cases that some are using capacitors between the drain and the source?
Hi!
I am kind of new in ''practical electronics'' and I have to design an electronic switch using a MOSFET to cause ignitions(few times per second..).
I guess that the main idea is to connect an NPN MOSFET between the power supply and the primary winding of the ignition coil.(I am going to...
