I'm looking for commercial already made driver for FUJI 1MBI300N-120.
Does someone know where to buy it ?

I say they have the input supply diode on the wrong side of the input
resistor.
Input swinging too much above supply, and *poof* ...

I do not use IGBTs, or their drivers so i could care less.
The complaint is,why are ICs designed wrong when there is an obvious
error (or more in some cases).
This is not the only company that has produced not-so-good stuff.

That series of IGBTs (1200 volts, 300 amps),have input capacitance of 20
or 30 nanofarads. To get them to switch quickly, they need several amps
peak gate current. Most designs I know of use discrete complementary
drivers, from positive and negative rails of about 30 volts, usually
driven from HP/Agilent, etc. complementary output optocouplers, as they
usually are used in a H-Bridge configuration.

It's all won and lost in how fast you can get the charge into and out of
the gate capacitance.

Look for Fuji application manual REH984 on the 'net.

They make a lovely bang when you get it wrong. Joerg would be proud :)
