Abstract

This study describes the design and implementation of power supply of dehop/rehop transponder of EQM(Engineering Qualification Model). We materialized the interface of the PLDIU and power supply of a satellite bus, and minimized the potential for the occurrence of such erroneous operation circuit ESD through the WCA of the space environment. We designed a reliable power supply through simulation for TID about space radiation and simulation of the vibration generated during it launched, and we confirmed that it satisfies the environmental test specification through the test space environment after production.

본 연구는 우주 인증용 대전자전중계기용 전원공급기의 설계 및 구현에 대해 기술하였다. 위성버스의 PLDIU(Payload Distribution and Interface Unit)와 전원공급기의 인터페이스를 제시하였고, 우주환경에 대한 WCA(Worst Case Analysis)를 통하여 SEU(Single Event Upset) 등의 발생에 대한 회로 오동작 가능성을 최소화 시켰다. 발사환경 시 발생하는 진동 및 우주 방사능에 의한 TID(Total Ionizing Dose)에 대한 시뮬레이션을 통해 신뢰성 있는 전원공급기를 설계하였으며, 제작 후 우주환경시험을 통하여 해당 구성품에 대한 환경 시험 규격에 만족함을 확인하였다.
