摘要

纳米卫星最初是为教育目的而开发的，现在正越来越多地用于商业用途。为了应对新的挑战，必须改进纳米卫星设备以提供更好的性能。这就需要使用+3.3V， +5V和+12V的DC-DC降压转换器将高电平直流电压降压到低电平。当前DC-DC降压变换器的发展趋势是低损耗、高功率密度和高效率。本文提出了一种+12V DC-DC降压变换器，并对DC/DC降压变换器进行了比较研究，以选择适合我们要求的变换器。结果表明，当输出电压为1时，效率可达88%。输出电流为2.1A。

DC/DC buck Converter Prototype for Educational Nanosatellite Power Sub-System

Nanosatellites, originally developed for educational purposes, are now being used for increasingly commercial applications. To meet the new challenges, nanosatellites equipment must be improved to provide better performance. This necessitates the use of DC-DC Buck converters of +3.3V, +5V and +12V to step down the high-level DC voltages to a low-level. Current trends in DC-DC buck converter development focus on low losses, high power density, and high efficiency. This paper proposes a +12V DC-DC Buck converter and conducts a comparative study between DC/DC Buck converters to select an appropriate one for our requirements. The results show a good efficiency of 88 %, with an output voltage of ll.93V and an output current of 2.1A.
