There is a need to develop improved film capacitors for high temperature, high energy density and high reliability applications. The work reported here has resulted in self-healing capacitor technology applicable to a wide variety of polymer film substrates that prevents catastrophic failures and provides safe, reliable operation in power electronic circuits. This paper describes the performance of 500-2000 Volt metalized film capacitors operating at up to 160°C under a variety of duty conditions. Data on equivalent series resistance (ESR) and power dissipation (DF), peak and Root Means Square (RMS) current ratings, and other critical performance parameters are presented. The features and benefits of both dry wrap-and-fill and liquid-impregnated hermetically sealed constructions are discussed. This work was sponsored by the US Army Research Laboratory.
