The use of wide band gap devices like GaN or SiC require new passive components, operated at elevated temperature and higher switching frequencies. SDU conducts research for new capacitor technologies like new polymer Aluminium electrolytic capacitors for voltage over 400 V or new dielectric materials for metallized film capacitors with increased dielectrically constants and a better thermal stability. This talk will put a glimpse on that research activities.
