Abstract

This study describes the design and implementation of digital Payload power supply. 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 a TID according to the vibration generated during the launch and space radiation environment, and found no problem in the function and performance through the test space environment after production.

본 연구는 디지털위성중계기용 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 ESD(: Electro Static Discharge) 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 기능 및 성능에 문제없음을 확인하였다.
