Spacecraft Power Systems
Abstract
A spacecraft needs electrical power for its operation. For a successful mission the power availability should be continuous and reliable. Power systems consists of three major constituients viz., Power Generation, Energy Storage and Power Conditioning and Distribution. The design considerations of these parts vary depending on the orbit and mission requirements. This talk explains the details of consideerations and schemes for Power System Design and Realisation in various types of spacecrafts
Bio-sketch for Speaker:
Ranganath S Ekkundi graduated in Engineering B.E. (E) with Electronics as specialization in 1976 and joined ISRO Satellite Centre ISAC (now renamed as U R Rao Satellite Centre), Bangalore in 1977. He made significant contributions in the area of Spacecraft Power Systems and played a key role in the development of Power Systems for the first Indian telecommunication satellite APPLE and first Indian remote sensing satellite IRS 1A. His major contribution is in the evolution of Power System Configuration for INSATs and GSATs which are Indian Geostationary Communication Satellites and had a lead role in concept through successful in orbit performance of Power Systems of CHANDRAYAAN & MARS ORBITER MISSION.
Rnganath S Ekkundi held various positions as Project Manager, Deputy Project Director and Associate Project Director for various projects of ISRO and served as Group Director (Power Systems Group) and as Outstanding Scientist and Deputy Director (Communications & Power Area) in ISAC. Further on also functioned as Prof Satish Dhawan Scientist at ISAC. He was
conferred with ASI (Astronautical Society of India) Award for Spacecraft and Related Technologies for the year 2008 and ISRO MERIT AWARD for the year 2012. He has published 12 technical papers on the topics of power systems and power electronics.
