Performance of the Perfluorocarbon Liquid/Plastic-Film Capacitor Technology in Pulse-Power Service - a Current Status Report

摘要

Some preliminary data are given from a program to evaluate the perfluorocarbon liquid/plastic film capacitor technology. Early results indicate lives of 10 exp 7 cycles at 1 kHz for polysulfone and polycarbonate films at 3.5 kV/mil stress levels. At 100 Hz, polysulfone performed without failure to 7x10 exp 6 cycles at 4.7 kV/mil before the test was halted. It is concluded that this capacitor system will permit at least an order of magnitude increase in energy density over current systems in repetitive discharge service, particularly for long life at high reliability.
