Meeting Motor Cost and Performance Goals through Integration and Thermal Management

Not Available Pulsed power systems need capacitors with energy densities inexcess of 10 kJ/kg (preferably 30 kJ/kg to keep the size of power conditioning systems manageable. Current dielectric materials are the major limiting factor inaccomplishing this goal. Foster-Miller proposes to develop a true polymeric dielectric material with extremely hgih deilectric constant, good dielectric strentgh and low loss, typical of high polymers. OUr approach is based on creating a dielectric which mimics the highly polarizable perovskite structure of titanatesi a true polymer. This propsal describes two classes of materials, and appropriate polymerization techniques to achieve this goal. In Phase I, we will synthesize monomers,and verify that they contain highly posarizable configuratesn via X-ray crystallography and dielectric measurements, and create a high molecurlar weight polymer with these monomers. In Phase II, we will scale-up the precesses, and teaming with Aerovox fabricate capacitors with energy density in excess of 10 kJ/kg, and energy storage above 2 kJ.
