Abstract:
NASA's new Space Exploration Initiative demands that vehicles, habitats, and rovers achieve
unprecedented levels of reliability, safety, effectiveness, and affordability. Modular and
intelligent electrical power systems are critical to achieving those goals. Modular electrical
power systems naturally increase reliability and safety through built-in fault tolerance. These
modular systems also enable standardization across a multitude of systems, thereby greatly
increasing affordability of the programs. Various technologies being developed to support this
new paradigm for space power systems will be presented. Examples include the use of digital
control in power electronics to enable better performance and advanced modularity functions
such as distributed, master-less control and series input power conversion. Also, digital control
and robust communication enables new levels of power system control, stability, fault detection,
and health management. Summary results from recent development efforts are presented along
with expected future technology development needs required to support NASA's ambitious
space exploration goals.
