To whom this may concern,
Hello.I truly apologize for this sudden e-mail.
My name is Shinichi Hiroshige from Toshiba Electronic Devices & Storage Corporation.
We are testing SiC-MOSFET module (Toshiba MG600Q2YMS3) usinig UCC21750/21732 (TI) gate driver borad.
We try double pulse test for mesurement switching charactoristic.
But 2nd pulse output from gatedriver board is unstable.
We can't try switching test of target voltage and current.
Current situation:VDS=300V/ID=150A
Target:VDS=600V/ID=600A
What do you think cause 2nd pulse output is unstable?
We tried disable DESAT curcuit, but similar results were obtained.
Best regards
