Radiation-Resistant, High-Efficiency Direct Current-Direct Current (DC-DC) Converters For Spacecraft Loads

ABSTRACT: The proposed program will provide three important products to the space electronics community: [A] An extremely rad-hard (estimated>3Mrad) high isolation and processor-free converter that can provide an (unregulated) intermediary voltage that can supply 6V/20V at 25W/40W respectively. [B] An extremely rad hard high isolation and processor-free converter that can provide an unregulated intermediary high voltage that can supply 120V/2000V at 120W/500W respectively. [C] A multi-output two-stage tightly regulated, rad-hard (estimated>0.6Mrad), voltage controller providing power for both low-voltage CMOS components (e.g. 1.2V) and ancillary devices such as A/D, D/A components (e.g. 15V). BENEFIT: The ability of Ceramic Core technology to provide large step-down ratio at power and high efficiency provides the first ceramics technology that can realistically replace cell-phone and laptop AC/DC adaptors in smaller, more highly efficient modules. The Phase I technology is already being hardware evaluated by Defense Primes for munitions and radio (SDR) applications.
