Proceedings of the 25th Intersociety Energy Conversion Engineering Conference.
A microwave beam power system using lunar orbiting solar powered satellite(s) and surface rectenna(s) was investigated as a possible energy source for the moon's surface. The concept has the potential of reduced system mass by placing the power sourc

Proceedings of the 25th Intersociety Energy Conversion Engineering Conference.
This paper analyzes various space electrical power system masses with particular emphasis on the power management and distribution (PMAD) portion. The electrical power system (EPS) is divided into functional blocks: source, interconnection, storage,

A scenario is presented wherein the interplanetary supply vehicles for the expansion of the Mars bases are nuclear powered and electrically propelled. For the initial buildup phase, supply vehicles need not return to Earth but could be utilized as a

SAE Technical Paper Series.
The need for a space power utility concept is discussed and the impact of this concept on the engineering of space power systems is examined. Experiences gained from Space Station Freedom and SEI systems studies are used to discuss the factors that m

As stand-alone photovoltaic (PV) energy systems have increased in size and diversity of loads, the importance of controls cannot be overstated. These systems represent "mini utilities" with the commensurate control requirements, albeit with the added

The high cost of energy from stand-alone photovoltaic (PV) systems dictates that the available energy is used in the most efficient manner possible. To do so requires careful attention to the operating characteristics of all the components of the PV
