Abstract :
Summary form only given. High energy (>5kJ) capacitors based on a number of different dielectric and electrode technologies are available for use in pulse power systems. Metalized electrode technologies allow higher energy densities to be achieved (up to 3 J/cc) at lower voltages, higher capacitances, and longer discharge timescales. Self-healing is a key feature of metalized film capacitors, allowing polymer film or paper dielectrics either to be used close to their intrinsic breakdown strengths, or providing greatly enhanced reliability and lifetime. Both metallic and insulating plastic cases can be combined with different dielectric/electrode winding types to provide optimized capacitors. While oil-filled capacitors still provide enhanced performance in high voltage applications, dry type capacitors are becoming popular. 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.
