Hello,
This is a Back-up Solution that i need to get to work while i cant purchase the semikron drive.
I've researched this design on a application note from vishay ( if im not mistaken ) on IBGT gate drivers with Opotocopoulers.
The IGBT datasheet states that the IGBT already has a gate resistor, thats why i didnt place one. Or did i understand it incorrectly ?
As for the opotocoupolers, the HCPL3180 can deliver up to 2,5Amp. Can you recommend any better optocoupoler to driver the IGBTs?
Thank you.
Best Regards
Bdrt
