Silicon-Carbide (SIC) Multichip Power Modules (MCPMS) For Power Building Block Applications, Phase II

In Phase I, APEI, Inc. proved the feasibility of developing a modular, expandable and fault tolerant SiC-based power system through the successful demonstration of a four-module SiC-based power system capable of dynamic reconfiguration allowing the system to continue delivering power to the load without interruption in the event of a module failure. These results show the feasibility of developing miniaturized SiC multichip power modules (MCPMs) to form a core power building block component. The MCPM building blocks utilize a distributed control and communications structure, with a communications network established between the core silicon-on-insulator (SOI) controllers of the MCPMs, but with no single controller in command of the system. The decentralized control and modular approach allow for the construction of highly flexible, auto-configurable, stackable power systems to be connected in series and/or parallel to increase overall system power handling capabilities. Moreover, the identical core MCPM building blocks could be used in many power electronics applications, while various specific functions such as source regulation, energy storage regulation, and motor drives could be achieved by the use of external components. In addition, the development of high-temperature MCPMs allows high levels of miniaturization, power density, and efficiency resulting in highly reliable, compact, modular, and inexpensive power systems.

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.
