ADDA: Almost direct drive architecture for solar high power electrical propulsion in new generation spacecrafts

2012 IEEE International Symposium on Circuits and Systems (ISCAS), 2012
This paper proposes a novel electrical power system architecture capable to efficiently transfer energy from a solar generator to high power electric thrusters of a spacecraft. The architecture is based on a maximum power point tracker that acts on a DC/DC converter connected between a subsection of the solar generator and the thrusters.

Solar electric propulsion by a solar power sail for small spacecraft missions to the outer solar system

Acta Astronautica, 2021
Abstract Outer solar system exploration by a small spacecraft using a solar power sail is investigated. A solar power sail is an extended form of a solar sail that has thin-film solar cells attached over its surface. This concept makes it possible to generate a large amount of power with less weight resources than conventional means.

The synergy of spacecraft electric propulsion and power

Space technology and applications international forum (STAIF - 97), 1997
The combination of spacecraft electrical power and on-board propulsion can consume as much as three-fourths of the mass of a spacecraft depending upon the mission. With the current emphasis on reducing costs (including launch vehicle costs) and on reducing the mass of future spacecraft it is apparent that the use of advanced spacecraft electrical power
