| Oct 10, 2013 at 15:32 | comment | added | Scott Winder | They're only available as limited samples at the moment; it was more of an example than a suggestion. There are other suppliers that produce intelligent drivers, but for obvious reasons, I'm much more familiar with the Renesas parts. Try a Google search for "igbt intelligent driver". | |
| Oct 10, 2013 at 15:15 | comment | added | Bob | @ScottWinder: how do I price these out/source these parts? I couldn't find them with the major supplier sites. | |
| Oct 10, 2013 at 15:08 | comment | added | Scott Winder | In terms of driving the IGBTs, you can save a lot of future headaches by using an intelligent power device. (Full disclosure: I work for Renesas, which produces the linked device.) | |
| Oct 10, 2013 at 14:37 | comment | added | Bob | @pjc50, I started at the beginning, and I'm working through it. I like that some substitute teacher decided to do this, and started pouring his time and resources into it. It is an impressive case of someone not taking "it's too complicated for you" for an answer. Because he's such a novice, there's no pride, and every mistake is laid out for the public to help out with and to learn from. But IGBT does seem like the way to go from what I'm seeing; I'm glad I asked here on SE! | |
| Oct 10, 2013 at 14:25 | comment | added | pjc50 | That thread is over six hundred pages of posts, starting in 2008! I skipped to the end and some of them mention an IGBT version of the design. They also describe some failure modes involving arcing between some of the high-voltage traces. Also, 30R as a MOSFET base resistor for that speed and current seems a bit high, although I've not done the math. | |

| Oct 10, 2013 at 13:58 | comment | added | Bob | Oh wow! At least some of them have free-wheel diodes! That can save some money. What do you use to drive them? | |
| Oct 10, 2013 at 13:53 | comment | added | Bob | I have heard of IGBT's, but I don't know them well enough and I haven't come across them for this application yet (though I have seen similar suggestions). Can someone give me a good pluses/minuses on FET vs. IGBT? | |
| Oct 10, 2013 at 13:50 | comment | added | Scott Winder | You can find IGBT modules at your favorite distributor that should meet your requirements--they can be a bit pricey, but ought to pay you back over time, as you've suggested. | |
| Oct 10, 2013 at 13:41 | comment | added | Scott Winder | Have you considered using an IGBT? | |

| Oct 10, 2013 at 13:07 | comment | added | Bob | End of life. So you could get it on ebay no doubt, but supply is uncertain and it's not really a good part to put in a design: you might not be able to find them if you might ever need to do repairs or if you might want to make one for a friend in the future. I stay away from EOL parts, and for something as commonly needed as a gate driver, there has to be an excellent (maybe better?) alternative. | |
| Oct 10, 2013 at 12:49 | comment | added | Andy aka | EOL? Does that mean you can't get it any more? | |
