High Speed and High Voltage Capacitors for Naval HPRF Directed Energy Applications

TRS Technologies, Inc. in collaboration with Oregon State University and ARC Technology proposes to continue developing volume efficient, fast discharge, high breakdown strength capacitors with stable dielectric properties for utilization in pulse power systems. The proposed ceramic capacitor will combine the best features of high energy density, low dielectric loss and high reliability. The capacitors developed on this program are targeted to have an operation voltage of 8,000~80,000V with 5~154nF capacitance, and exhibiting discharge times much less than 10 ns. The high energy density dielectric material will enable this performance in a package size < 8 ~< 100 cm3. Nonlinear paraelectric material with high energy density will be fabricated with fine grained and defect free microstructure to have high breakdown strength, high energy density and high reliability through fine ceramic processing and design optimization.
