Dielectrics for Power Electronics Applications

Research output: NRELPresentation

Abstract

This presentation discusses the role of dielectric materials in power electronic packages. Two dielectric technologies - a dielectric material film-based substrate for insulation and a dielectric coolant - are discussed. The thermal performance benefits of dielectric film-based substrate in comparison with traditional direct-bond-copper substrates are studied through finite element analysis. Also, a novel cooling concept based on dielectric liquids that can contact electrically active surfaces are presented.
