Re: IGBT Types

Original poster: Terry Fritz <teslalist@xxxxxxxxxxxxxxxxxxxxxxx>

Hi Malcolm,

I am using International Rectifier IRG4PF50WD IGBTs. I have a current limit adjustable from 0 to 500 amps. I have run these before in the OLTC days to 750 amps. I am driving the gates with about 25 volts to be real sure they are turned on hard. I run about 1500 watts. They have a 60C thermal switch that has never tripped. They are cheap and easy to get from DigiKey for about $8 each. All details are at:

Cheers,

        Terry

Greetings all SS Coilers,
                           I'd appreciate it if those who are using
IGBTs would let me know the part numbers/types they are using and
power levels the coils they are being used in are run at (or have
been run up to non-destructively). If this is deemed to be noise then
I'd be grateful to accept replies offlist.

Thanks in advance,
Malcolm
