Recent advances in capacitor technology with application to high frequency power electronics and voltage conversion

Electrolytic and electrostatic capacitor manufacturers are working closely with the power conversion industry to reduce component size, extend current handling ratings and improve parasitic behavior in the low and high pass power train circuits germane to power conversion. Some of the more dramatic and market-wise important capacitor component development trends are covered in this paper. To limit its scope, this paper concentrates on trends for capacitors used in large volume, high frequency power converters
