DEVELOPMENT OF A POWER-BY-LIGHT SYSTEM FOR SPACE APPLICATIONS BASED ON GaAsMULTIPLE PHOTOVOLTAIC CONVERTERS

摘要

The purpose of this work is to develop a power-by-light system in order to power an electronic circuit which reproduces the performance of a real control system in a satellite. The circuit, a MOSFET regulator used tocontrol the activation-deactivation of solar modules in the satellite solar array, is currently powered using aconventional power supply, being the aim of this project to evaluate the possibility of substituting the latter by an optical powering link The work includes the evaluation of the characteristics of the application, the development of the optical powering link and its characterization, detailing the measurement of the efficiency in every component; and the performance of the powered equipment. This way, the possibility of incorporating optical powering links to space applications is assessed, laying the foundations for later projects.
