Description

Development of a new generation of high-energy-density capacitors for power conversion/conditioning systems will be beneficial to reduce the size, weight, and cost of resultant transmit and receive (T/R) modules in modern radar and electronic warfare transmitters. Among capacitor technologies available, multilayer ceramic capacitors (MLCCs) and polymer-ceramic composite dielectric based capacitors are receiving more attentions. At present these capacitors, however, suffers from limitations such as low energy density, low voltage rating, poor stability in a wide temperature range and high costs. Therefore this project is to develop a novel class of high-voltage, high-energy-density MLCCs based on an innovatively designed nanocomposite dielectrics. In addition, the proposed dielectrics and resultant capacitors can be processed through scalable and cost-effective methods in good compatibility with existing industry technologies and thus potentially low costs for mass productions. In Phase I, we will demonstrate the feasibility of the proposed technology through material design, processing, device prototyping and testing. In Phase II, both material and device processing will be further optimized. Based on the results, scaling-up will be carried out and the full-scale prototypes of MLCCs with targeted properties will be demonstrated through more extensive tests with a focus on high energy density and enhanced temperature stability.
