Design and Implementation of a Microsatellite Electric Power Subsystem

摘要

The design and implementation of the CKUTEX microsatellite electrical power system is described in the paper. An increasing number of space experiments relies on the use cheaper, lighter microsatellites to accomplish the mission. With the smaller size of satellite, appropriate power management is important. To enhance the efficiency, peak power tracking (PPT) technique is one of the solutions to harvest more power from solar panel. Several PPT techniques suitable for microsatellite applications are implemented and compared in the paper. With all the considerations, one power system design suitable for the mission is thoroughly investigated, designed, and implemented.
