A checklist of what can zap your power electronics or insulation

This paper is a condensed version of papers presented at the Applied Power Electronics Conference in 1997 and 1998. There is no checklist in this shortened version, only insulation applicable topics. Hopefully, more recent information can be presented orally at EIC 2007. Design literature for dealing with corona as found in switching power supplies for high altitude aircraft or in lamp ballasts does not contain the effects of the switching frequency on corona inception or extinguish voltages. Test data is presented showing these effects. Design techniques for corona are also discussed.
