U user1453 New Member Mar 30, 2007 #1 The IGBT in question is https://www.electro-tech-online.com/custompdfs/2007/03/0900766b8010b65e.pdf I was Hoping I could drive it using a pair of pnp and npn transistors connected to +/-12V, the IGBT will be switching 300v in a short puls is +/- 12V enough?

Click to expand... In the attached files you can see a portion of schematic diagram and the Gate-Emitter Voltage (waves) of your IGBTs used in a welding inverter wich I have repaired recently. I used a 0-10MHz scope. Attachments igbtdrv.png 8.2 KB · Views: 6,138 igbtwave.jpg 44.8 KB · Views: 520
