PPPS-2013: Performance comparison of high energy capacitor technologies part 1: Discrete foil electrodes

High energy (>5kJ) capacitors based on a number of different dielectric and electrode technologies are available for use in pulse power systems. Discrete foil electrode capacitors are appropriate for higher voltage, lower capacitance, and faster discharge. Discrete foil capacitors offer the highest peak power and average power capabilities and elements can be connected in series to achieve extremely high voltages, up to a few megavolts. Both metallic and insulating plastic cases can be combined with different dielectric/electrode winding types to provide optimized capacitors. This work will compare the capabilities of different capacitor technologies for a wide range of operating conditions and provide guidance in selection of high energy capacitors for future applications.
