Wide Temperature, High Energy Density Capacitors for Power Conditioning Systems

TRS Technologies, Inc. proposes to develop ceramic capacitors as power conditioning capacitors for electrically driven military weapon systems. The proposed ceramic capacitor will combine some of the best features of high energy density, low dielectric loss, and high temperature stability. The capacitors developed on this program will have energy density >4J/cc, low power dissipation, and a wide working temperature range up to 300¡ÆC. In Phase I, ceramic multilayer capacitors will be fabricated and evaluated. This will include selection of the optimum material from paraelectric and linear dielectric ceramics, design and fabrication of capacitors and evaluation of capacitors such as breakdown strength, energy density and temperature stability. Graceful failure mode will be attempt by designing internal structure for self healing to improve the reliability of multilayer capacitors.
