Lightweight Power Control Units and Power Distribution Control Unit for Satellites

Abstract

To increase the ratio of mission payloads on spacecraft, compact and lightweight electrical power subsystem (EPS) is demanded. Previously, since the EPS of our program was not in line with the trends, mass ratio and handling power, of the global market, a new EPS was developed to halve the ratio of mass and handling power in line with global requirements. This paper presents the new technologies adopted to achieve weight reduction, introduce ideas and developments in power control units and power distribution control unit.
