Decentralized Nonlinear Controller Based SiC Parallel DC-DC Converter, Phase I
Completed
Description
This proposal is aimed at demonstrating the feasibility of a Decentralized Control based SiC Parallel DC-DC Converter Unit (DDCU) with targeted application for NASA's International Space Station Program and Satellite Power Systems. The proposed DDCU has three key features: a) "true" redundancy for parallel DC-DC converter based on a novel concept developed at the University of Illinois at Chicago, b) a novel nonlinear hybrid controller that achieves enhanced robustness and wider stability margin and yet achieves interleaving to reduce output current ripple, and c) SiC based power stage yielding higher breakdown voltage, temperature-sustenance, and radiation-hardness capabilities for the DDCU leading also to higher power density as compared with Si based power stage.

How to get involved
This is a mature technology (TRL 7+) — the realistic path in is usually NASA's Technology Transfer Program: licensing an existing NASA patent, or a Space Act Agreement to use NASA facilities/expertise directly. NASA also runs a startup licensing program with no upfront fee for companies formed to commercialize a specific NASA technology.
None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
