OBSERVATIONS ON COMPETING MECHANISMS GOVERNING THE C-V RESPONSES OF NONLINEAR CERAMIC CAPACITORS

Ceramic capacitors with nonlinear C-V response find application in pow er-electronic snubber switching circuits at higher voltages, Here, the ac and in-situ switching C-V responses of commercial multilayer and h igh-voltage disc capacitors are compared in relation to their postulat ed ferroelectric grain and p-n junction grain-boundary contributions, with a view to optimizing component performance through an increased u nderstanding of such interrelated mechanisms.
