Power electronics, along with computer and microprocessor technology, impacts nearly every sector of the U.S. economy including automobiles, electric utility, pollution control, communications, computer systems, consumer electronics, and factory automation. For commercial applications, the proposed new packaging technology can be used in its current form or scaled down to medium or conventional temperature range with a significantly reduced cost, making it a viable and economical option for large commercial markets such as hybrid electric vehicles, renewable energy conversion, and power supplies.
Wide operating temperature power semiconductors for space power systems and science missions such as Earth Orbiting, Venus, Europa, Titan and Lunar Quest.","description":"Silicon carbide (SiC) and other wide band-gap semiconductors offer great promise of high power rating, high operating temperature, simple thermal management, and ultra-high power density for both space and commercial power electronic systems. However, this great potential is seriously limited by the lack of reliable high temperature device packaging technology. The objective of this proposed research is to develop a ultra-compact, hybrid power module packaging technology based on the use of double leadframes and direct leadframe-to-chip transient liquid phase (TLP) bonding that allows device operation up to 450 degrees Celsius. The unique advantages of this innovative solution include very high current carrying capability, low package parasitic impedance, low thermo-mechanical stress at high temperatures, double-side cooling, and modularity for easy system-level integration. The new power module will have a very small form factor with 3-5X reduction in size and weight from the prior art, and capable of operating from 450C to -125C.","startYear":2011,"startMonth":6,"endYear":2013,"endMonth":5,"statusDescription":"Completed","principalInvestigators":[{"contactId":229152,"canUserEdit":false,"firstName":"John","lastName":"Elmes","fullName":"John Elmes","fullNameInverted":"Elmes, John","primaryEmail":"jelmes@apecor.com","publicEmail":true,"nacontact":false}],"programDirectors":[{"contactId":206378,"canUserEdit":false,"firstName":"Jason","lastName":"Kessler","fullName":"Jason L Kessler","fullNameInverted":"Kessler, Jason L","middleInitial":"L","primaryEmail":"jason.l.kessler@nasa.gov","publicEmail":true,"nacontact":false}],"programExecutives":[{"contactId":215154,"canUserEdit":false,"firstName":"Jennifer","lastName":"Gustetic","fullName":"Jennifer L Gustetic","fullNameInverted":"Gustetic, Jennifer L","middleInitial":"L","primaryEmail":"jennifer.l.gustetic@nasa.gov","publicEmail":true,"nacontact":false}],"programManagers":[{"contactId":62051,"canUserEdit":false,"firstName":"Carlos","lastName":"Torrez","fullName":"Carlos Torrez","fullNameInverted":"Torrez, Carlos","primaryEmail":"carlos.torrez@nasa.gov","publicEmail":true,"nacontact":false}],"projectManagers":[{"contactId":3164225,"canUserEdit":false,"firstName":"Brent","lastName":"Gardner","fullName":"Brent Gardner","fullNameInverted":"Gardner, Brent","primaryEmail":"Brent.G.Gardner@nasa.gov","publicEmail":true,"nacontact":false},{"contactId":461333,"canUserEdit":false,"firstName":"Theresa","lastName":"Stanley","fullName":"Theresa M Stanley","fullNameInverted":"Stanley, Theresa M","middleInitial":"M","primaryEmail":"theresa.m.stanley@nasa.gov","publicEmail":true,"nacontact":false}],"website":"","libraryItems":[],"transitions":[{"transitionId":66344,"projectId":9661,"partner":"Other","transitionDate":"2011-06-01","path":"Advanced From","relatedProjectId":8929,"relatedProject":{"acronym":"","projectId":8929,"title":"High-Temperature, Wirebondless, Ultra-Compact Wide Bandgap Power Semiconductor Modules for Space Power Systems","startTrl":2,"currentTrl":3,"endTrl":3,"benefits":"The proposed concept will have a profound impact on power electronics and energy conversion technologies and help to conserve energy and environment, as well as to reduce the nation's dependence on fossil fuels.

The NASA SBIR and STTR programs fund the research, development, and demonstration of innovative technologies that fulfill NASA needs as described in the annual Solicitations and have significant potential for successful commercialization. If you are a small business concern (SBC) with 500 or fewer employees or a non-profit RI such as a university or a research laboratory with ties to an SBC, then NASA encourages you to learn more about the SBIR and STTR programs as a potential source of seed funding for the development of your innovations.
The SBIR and STTR programs have 3 phases:
The SBIR and STTR Phase I contracts last for 6 months with a maximum funding of $125,000, and Phase II contracts last for 24 months with a maximum funding of $750,000 - $1.5 million.
Opportunity for Continued Technology Development Post-Phase II:
The NASA SBIR/STTR Program currently has in place two initiatives for supporting its small business partners past the basic Phase I and Phase II elements of the program that emphasize opportunities for commercialization. Specifically, the NASA SBIR/STTR Program has the Phase II Enhancement (Phase II-E) and Phase II eXpanded (Phase II-X) contract options.
