Any good articles in using IGBTs in linear mode? With all due respect for the uselessness of SPICE when you can't do the work on paper -- does anyone know how good a SPICE model designed for an IGBT in switched service might work in linear mode? Who tends to have better models for linear service? Whether anyone has models specifically for IGBTs in linear mode? TIA -- IGBTs seem to ...

I had some electronics in a storage building, which flooded. I figured that most of it is junk, but I wiped it clean and put some of the stuff outside in the sun to bake dry. So far, much of it works. But two items, a GPS and a Police Scanner, both with LCD screens have very faint screens. I kind of think the water affected the LCD screens. Is there any way to get them LCD screens to work...
