Development and Characterization of a >1kV Power Electronic Capacitor for >300 degree C Operation

Abstract : Currently, a large suite of electronic systems used in commercial and industrial applications (which include, but are not limited to, automotive, nuclear power, and well logging systems) require cycle-life performance that would benefit significantly from components designed and optimized for higher temperatures (20 deg C to 60 deg C) under harsh environmental conditions. This paper presents the development, characteristics and life tests of a > 1 kv, > 30 deg C reconstituted mica paper power electronics capacitor system, including a full-size 2.4 microfarad unit. It should be noted that reconstituted mica paper capacitors are used in a variety of applications, and that they are particularly well suited for use in high voltage, high temperature electronic systems: silicone impregnated mica paper capacitors are available for operation at 260 deg C.
