Abstract
Advances in radar systems are pushing the limits of present radar power supply technology. To enable new concepts, such as active array radar systems, significant improvements (i.e., power densities >200 W/in3, efficiency > 90%, transient response < 10 s, etc.) in radar power supply technology is required. To achieve these goals, the volume of present state-of-the-art silicon-based power electronics systems must be cut in half, while maintaining (and in most cases improving) the efficiency of those systems. Such high power density systems will face tremendous thermal challenges since more power per unit of volume under similar efficiency requirements and electronics packaging technology means higher temperature rise. Present high power density Si-based systems are severely limited by the thermal performance of active and passive components as well as electronics packaging technology, and therefore, the achievement of the target radar power supply goals cannot be attained without a revolutionary change in radar power supply technology. This Small Business Innovation Research Phase I project seeks to develop highly efficient (>94%) and compact (>250 W/in3) next-generation radar power supplies utilizing the now emerging silicon-carbide (SiC) power devices.
