TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
VPT proposes an innovative concept whereby complex NASA space power electronic systems can be configured using a small number of qualified hybrid DC-DC converter and EMI filter modules. This significantly reduces nonrecurring engineering in the design of space power converters. In the SBIR Phase I, VPT configured a space station power converter using a VPT standard product hybrid DC-DC converter and EMI filter. The system met all Space Station power quality requirements including the very challenging input impedance requirement. Two engineering units were developed and went through a full battery of space station power quality tests NASA-JSC. The approach also demonstrated a significant size and weight savings. The phase II workplan includes: (a) selection of three NASA power system applications across different branches for development of detailed power requirements, (b) design and build engineering units of each of these systems using a modular approach of VPT hybrid converters and subject each to engineering tests, (c) make necessary changes to selected VPT standard product hybrid converters in order to meet NASA requirements for design, parts selection, element evaluation, screening, radiation hardness, and qualification, (d) build a qualification unit for one system and subject it to formal qualification tests.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Potential NASA-JSC Space Station applications include power converters for the IBM A31 Notebook Computer PC used buy the astronauts. Potential NASA-GSFC applications include the power system for the JWST. Potential NASA-GRC applications include the power system for the CEV and lunar orbiter. Potential NASA-JPL applications include a space-borne GPS receiver for attitude and orbit determination. Potential NASA-GSFC applications include the power system for the JWST.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Potential non-NASA applications include many commercial satellite systems and the power system for the GPS III satellite system.
