The Impact of High Energy Density Capacitors with Metallized Electrode in Large Capacitor Banks for Nuclear Fusion Applications
Abstract
Power supplies for Inertial Confinement Fusion (ICF) lasers require large capacitor banks. As capacitor bank size increases, reliability, expressed as Mean-Time-Between Failures (MTBF) is reduced, for a given capacitors design. Metallized electrode capacitors exhibit more predictable failure characteristics than traditional foil designs, thus increasing MTBF for some applications. In addition, their "soft" failure mode gives facility operators flexibility to schedule capacitor bank maintenance. Experience with the design and testing of a metallized electrode capacitor for a 13 MJ bank is presented. Weibull statistics are used to predict performance on the 13 MJ bank, and on a proposed 250 MJ facility. While the Beamlet capacitor data is specific to Aerovox capacitor part number KM223YW215D01, much of the information is applicable to high voltage metallized electrode capacitors in general.
