IGBT driver board

[mrbigh]

many have been sold as a bare PC Bd. and with a parts kit. Never heard a dissatisfaction.
I'm using a double configuration with 4 IGBT modules since a while

Horacio, are the boards you had made the same as the BG2A boards?
Do you have them, and the parts, and what costs?
Did you mean to say you have your EV running using them?

I thought I read the fault circuit isn't used?
I have a precharger control that detects a fault, but if the driver can do it without the slow micro handling it, this is better and faster.

thanks, jack

the only difference between this board and the BG2A board is the parts are labeled slightly differently on this one, so you can't just blindly follow the powerex parts list, or you'll end up with parts in the wrong places. it's pretty easy to figure out where the parts are supposed to go though, by looking at the powerex artwork and comparing it to the BOM

Now, I am working at the (almost) final stage....wiring the driver to the IGBTs....

[isaac_alaska]

how many igbt's are you driving?

[KUSAW]

This stage I am working with 2x400 A IGBTs

[isaac_alaska]

i think using the bg2a board with both vla drivers on it is overkill for 2 igbt's, but that's just my opinion

Isaac is right. 2 vla-501 is overkill for 2 400A modules. Even 1 VLA is overkill for 2 modules. I would use 1 and parallel the igbt's with gate resistors for each module.

thank you very much for suggestion, I'll follow your direction..
thanks again Brothers...

[KUSAW]

Gentlemen,
I also have the other 2 IGBTs, each 1200A, can I drive them each? or have to do it paralel?
thanks
