Other Parts Discussed in Thread: UCC5350, UCC21551
Hi
I'm testing UCC5350 for SiC driver in PMSM control application(600VDC input).
I use bootstrap method to give the high side UCC5350 Power supply.
The waveform of the Vgs is a little strange, it has a voltage overshot(about 3.5V) when turning on and negative negative transients when turning off.
I use the high voltage differential probe(TMDP0200) of Tekronix for Vgs measurement.
Is this a normal phenomenon,or is there something wrong with my test process?
