Three Phase Resonant DC Power Converter for Ion Thrusters, Phase II

Our phase 1 study has revealed many significant benefits of a new class of DC-to-DC power converters with performance that cannot be matched by current flight power systems. The goal of low stored energy has been demonstrated while producing a record-breaking efficiency of 95.5%. This new converter claims this remarkable accomplishment not at just one full power point but at two distinct points. The converter was able to delivery its full rated power of 1kW at 2850V and 5000V load voltages without any physical adjusts. This new converter demonstrated low arc energy and rapid recovery response while powering NEXIS like sub-scale ion optics at Colorado State University. The 1kW prototype's stored energy was less than 1.9mj at 5000Voutput and less than 700?j at 2850V output. In phase 2 we will integrate this new technology into a computerized ion thruster test system capable of delivering 24kW screen power. The planned test system will serve to gain confidence with the new topology and to initiate power system designers to an exciting new technology.

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.
