Insulated Gate Bipolar Transistor
I recently got to see some of these insite of a "small" DC to AC inverter turning a solar array into AC power. (50kw worth) The engineer forgot what the official name was and emailed me today with this link and a description.
I'm impressed by his follow-thru, to a casual question during a tour, as well as the device. Now I want to use some somewhere... build my own electric car controlling circuits or lightning creator..
and for some reason, I get different connotations when I see the abbreviation IGBT.

I would love to build an electric car controller. And I still wanna replace the Atmel AVR controlling relays Christmas light controller I built a few years ago with a similar driving TRIACs that can do brightness modulation, for fade-in and out and lower overall intensity...

These might be a little overkill for the christmas lights.. unless you go overkill for christmas lights.

Yeah, I think a TRIAC would do fine for lighting.
But electric car motors... man, there's a lot o' cool stuff to learn about driving motors...

[edit history]
Oh, hey! I've used one of these things to control an array of halogen lights. I was working with an artist who made a big sculpture of a geode, and he wanted it to glow with a pulse like the MacBook sleep light. I used an AVR to PWM the control line on a big fat SSR, which is basically an IGBT in a fancy case with screw-terminals. Worked great. It was hard to believe it was really that simple.
I have a temporarily shelved project to convert a motorcycle to run on battery power - I've been assuming I'd get an Alltrax AXE7245 to control the motor, but if it's just an even bigger IGBT inside, maybe I can do that myself...
We will not edit your comments. However, we may delete your
comments, or cause them to be hidden behind another link, if we feel
they detract from the conversation. Commercial plugs are fine,
if they are relevant to the conversation, and if you don't
try to pretend to be a consumer. Annoying endorsements will be deleted
if you're lucky, if you're not a whole bunch of people smarter and
more articulate than you will ridicule you, and we will leave
such ridicule in place.
