Title: Ultra-Lightweight, High Efficiency Silicon-Carbide (SIC) Based Power Electronic Converters
Agency: NASA
Contract: NNC06CA21C
Award Amount: $599,995.00
 

Abstract:

In Phase I of this project, APEI, Inc. proved the feasibility of creating ultra-lightweight power converters (utilizing now emerging silicon carbide [SiC] power switching technologies) through the successful demonstration of power switch operation up to 500 oC. The goal of Phase II will be to design, fabricate, and fully test SiC based DC/DC converters that can achieve high power density and ultra-lightweight by operating the power switches at high junction temperatures. Present state-of-the-art silicon based spacecraft power systems operate at a power density of approximately 1.5 W/cm?, while the high temperature SiC based power converters proposed by APEI, Inc. in this project will operate at a power density of approximately 4.5 W/cm?, or 3? the density of present high performance silicon based systems. Theoretically, if the full potential of silicon carbide switches could be realized (junction temperature operation in excess of 600 oC), an order of magnitude power density improvement could be achieved.APEI, Inc. is proposing to fabricate up to three prototype high density (4.5 W/cm?) DC/DC converter designs: (1) 28V in / 5V out @ 25 watts(2) 28 V in / 5V out @ 100 watts(3) 28 V in / 5V out @ 1 kW
