Accommodation Aspects of Electric Propulsion with Power Processing Units and the Spacecraft [PDF]
9th Annual International Energy Conversion Engineering Conference, 2011 The accommodation of Electric Propulsion and the associated Power Processing Units within a Spacecraft must lead to an integrated system providing full function and performance. This process starts with a proper specification of the electrical interface between thrusters and electronics, the handling of high voltages in a distributed harness, the ...

Evaluation of cryogenic power conditioning subsystems for electric propulsion spacecraft
IECEC 96. Proceedings of the 31st Intersociety Energy Conversion Engineering Conference, 2002The power requirement of vehicles designed to transport cargo supporting a piloted expedition to Mars is in the range of megawatts. Therefore, it is imperative that the megawatt class power processing unit designed for high-power nuclear electric propulsion vehicles using turboalternators and advanced magnetoplasmadynamic (MPD) thrusters should be such

Solar System Research, 2016
The problem of optimizing the interplanetary trajectories of a spacecraft (SC) with a solar electric propulsion system (SEPS) is examined. The problem of investigating the permissible power minimum of the solar electric propulsion power plant required for a successful flight is studied. Permissible ranges of thrust and exhaust velocity are analyzed for
