Title: High Efficiency Three Phase Resonant Conversion for Standardized Architecture Power System Applications
Agency: NASA
Contract: NNC06CB37C
Award Amount: $69,997.00


A low-cost, standardized-architecture power system is proposed for NASA electric propulsion (EP) applications. Three approaches are combined to develop a system that will meet current and future NASA needs and exceed currently available power processor unit (PPU) performance in terms of electrical efficiency, specific mass (kg/kW), and cost. The approaches include the use of (a) high-efficiency, 3-phase, dc-dc converters to minimize cooling requirements, mass, and parts count and maximize reliability and efficiency, (b) modularized and standardized sub-system design and fabrication techniques to accommodate power output scaling and re-configuration for specific ion thruster designs without the need to re-qualify hardware, and (c) attention to cost and manufacturability issues that will allow the implementation of electric propulsion systems on future NASA missions without the hidden costs of "hard-to-build" and "hard-to-scale" designs that are currently available. The innovations proposed herein will allow NASA to obtain the flexibility and performance it needs in power processors for electric propulsion systems while ensuring that their cost and difficulty of fabrication is low.
