Reduced Shielding, Rugged, Scalable-Electrical Power Converter for Fission-Power Systems

After a very successful Phase I program, where QorTek has been investigating and developing the design of a lsquo;KILOPOWERrsquo; relevant AC-DC converter that is highly compact (extremely power dense), lightweight, reliable, and designed to rapidly move onto an environmentally robust and HiRel version in Phase II.nbsp; Our primary focus has been NASA Advanced Stirling Radioisotope Generator (ASRG) Ramp;D efforts led at NASA by Glenn (GRC) in support of Human Exploration and Operations Mission Directorate (HEOMD) goals. Specifically, this project aims to provide a radiation hardened, scalable, modular AC-DC micro-grid power converter system scalable to 10-40kW for a space power dc bus applications. To ensure excellent high efficiency energy transfer, this advanced Kilopower AC-DC converter is a 2-stage design comprised of a (NASA-developed energy balancing) innovation in Power Factor Correction (PFC) front-end stage feeding a Very High Power Density (VHPD) converter based on QorTek recent patent awarded ultra-dense switchmode Phase Shift Resonant (PSR) and have been proven to meet the ASRG concept needs. The program focus is to mesh with advanced fission-based Stirling converter unit technology being developed by NASA/DOE
