Analisis Pengaturan Sistem Catu Daya Pada Satelit Nano

Abstract

The success of a nanosatellite mission is depend on the reliability of the Electrical Power System (EPS) to ensure the subsystems on the nanosatellite working properly. Therefore, an effective power distribution control is required. This research will explain how to distribute electrical power effectively to the subsystems according to the condition of the nanosatellite (sunlight or eclipse). To illustrate this, a simulation and analysis of the EPS power management module design consisting the LT3757 boost converter and LT3652 battery charger were performed. From the simulation results, it will be seen that when the nanosatellite is exposed to the sun, the system will distribute the power to the load using the input power from the panel surya that has passed the boost converter component (12 Volt), while charging the battery until it’s fully charged (7,4 Volt). But during the eclipse phase the system will supply the load with the power generated by the battery (7,4 Volt)
