Design and test of SiC circuit board for MIST satellite : KTH Student Satellite MIST
Abstract: This paper describes work related to the “Miniature Student Satellite” (MIST) project and the ”SiC in Space” project, located at KTH, Stockholm, Sweden. The goal of the MIST project is to launch KTH’s first student satellite into space, carrying multiple scientific experiments where SiC in Space is included. This thesis contains a compilation of three MIST-related bachelor theses that were carried out at KTH in the spring of 2016, primarily consisting of constructing and testing circuits for power supply and measurements for the SiC in Space part of the satellite. A printed circuit board has been developed, which accommodates experiment circuits to evaluate the features and functionality of silicon carbide components in a space environment, and power the supply to the SiC in Space and the Piezo LEGS projects. The development includes designing, assembling and testing the PCB according to the MIST team’s demands and requirements. Emphasis has been laid on electrical safety to ensure that the design can not short circuit the satellite battery, as well as EMC considerations to minimize the EMI between different parts of the satellite. Final testing of the hardware has not been executed due to an ordering error and time shortage, wherefore the planned test protocol has been included for future work.
