Microsatellite Power Control and Distribution Unit For The Innosat Platform

摘要

The Power Control and Distribution Unit (PCDU) described in this paper is a custom design for the InnoSat satellite platform. Particular attention is given to the architecture, design techniques and general failure mitigation approach that has been adopted to meet the low cost constraints of the platform while maintaining reliability for its entire mission lifetime. A point of importance is the scalability of the design in order to meet different payload power demands from mission to mission while minimizing NRE work. The very important areas of component selection, testing and qualification are also described. In order to quantify some of the topics discussed, the description is mostly focused on the PCDU of the first InnoSat based satellite named MATS and which is expected for launch at 2018.
