Radar Power Sources and Power Conditioning

VPT proposes a high efficiency, high density, power converter that can support the requirements of wide band gap RF devices for Radar applications. The power converter will be modeled after VPT's existing 270V, half brick, 200W, 85% efficient design butwill demonstrate significantly higher power density, efficiency, and operating temperature range by employing several new technologies. These include (1) new Silicon Carbide Schottky diodes (2) chip scale, embedded power packaging with advanced thermalmanagement (3) ASIC controller, (4) high frequency magnetics design. In the Phase I research, VPT will perform the following: (1) develop power requirements for the next generation solid state arrays using wide bandgap devices, (2) perform the electricaldesign of a high frequency power converter with silicon carbide rectifiers that meets the requirements, (3) breadboard the design to verify the electrical performance, (4) perform a preliminary packaging design chip scale embedded power packaging in a fullbrick form factor, (5) perform a preliminary ASIC controller design. The goal is to obtain a power density of 200W/cubic inch, an efficiency of 92%, and an operating temperature range up to 125C. A 270V, high density, high efficiency, full brick powerconveter can be applied to a number of military and commercial aircraft applications
