Victor Burnouts
This year for the first time we had recurring problems blowing victors.
The (6) FETs on one direction of the “H” would all burn out for some reason. Luckily no underlying damage was done, so it was only a matter of replacing 90 cent FETs, but we haven’t come up with a definitive reason for the failure.
The obvious suspects are metal chips, but the victors seemed to be clean when they are pulled apart.
Any of you have unusual victor issues this year, or have other interesting theories on blowouts?
