Technical Abstract

Many existing or proposed NASA small propulsion systems and advanced scientific instruments will require high voltages at medium to high power levels to function. Such space power supplies are generally bulky and lossy and, as missions increasingly migrate to ever smaller platforms, there will be an increasing need to substantially reduce the size/weight costs of providing such on-board power access.  The proposed program will address this increasingly expanding space power requirement by developing a new RadHard high performance / high voltage / high power (40V to 2kV at >94% efficiency) dc-dc converter capability that leverages new availability of high frequency (> 20 MHz) power MOSFET components. Utilizing this high frequency switching enables the use of core-less inductors that considerably reduce size and weight of the converters; integrating advanced magnetic materials will even further reduce size/weight costs.  The design moreover incorporates new tunable filter technology along with a tunable matching network as to provide for a far larger near-optimal performance window than is presently available to any NASA (switching) design which introduces significant agility to be used across a wide-range of NASA mission needs and has potentially wide impact to all NASA converter designs.

Potential NASA Applications

The new high performance/high voltage/high power supply solution has a wide range of applications to SmallSat/CubeSat orbital maneuvering systems and scientific instruments that increasingly need on-board high voltage availability.  The technology is synergistic with investments by NASA to develop SmallSat/CubeSat micropropulsion systems. The technology could significantly impact surface exploration missions by providing mission power solutions that greatly reduce lander size/weight loads.

Potential Non-NASA Applications

The technology proposed directly expands our existing expanding markets, dominated by the needs of the munitions and missiles and oil & gas exploration industries, for high performance/high voltage/low power supply solutions.  We are also closely allied with a major supplier of high voltage/high power supply solution to the medical and wafer fabrication markets that this would greatly impact.
