Abstract

Space industry is on a rise and satellites are being used in plethora of applications. Smaller satellites such as Cube-Sats and Nano-satellites are turning out to be extremely useful for research purposes as they are cost and space effective. In order to support and promote space research in academic institutions, student satellite projects are being encouraged. These projects help students to work closely with space industry professionals in order to gain knowledge about satellites and their functioning. However a satellite consists of different components each one of which has a different design approach and require different technical expertise. In this paper a preliminary approach for designing an Electrical Power System for a CubeSat is proposed along with modelling and simulation of the same in LTspice which is a spice based simulation software. Complete Electrical Power System has been designed for both Direct Energy Transfer and Maximum Power Point Tracking type architectures and simulation results for the same have been presented.

基于LTspice的立方体卫星电力系统初步设计与仿真

航天工业正在兴起，卫星正被用于各种各样的应用。立方体卫星和纳米卫星等较小的卫星对研究目的非常有用，因为它们具有成本和空间效益。为了支持和促进学术机构的空间研究，鼓励学生进行卫星项目。这些项目帮助学生与航天工业专业人员密切合作，以获得有关卫星及其功能的知识。然而，卫星由不同的部件组成，每个部件都有不同的设计方法，需要不同的技术专门知识。本文提出了一种立方体卫星电力系统的初步设计方法，并在基于spice的仿真软件LTspice中对其进行了建模和仿真。针对直接能量传递和最大功率点跟踪两种结构设计了完整的电力系统，并给出了仿真结果。
