|Project Summary||Project Information|
P13271,the team working on this project, has been tasked with providing AMSAT with an engineering prototype of a 7 Watt Maximum Power Point Tracker (MPPT). This project will be further developed into a flight ready design to be launched into orbit around 2015. The scope of this project includes providing a NASA derated and radiation tolerant engineering prototype MPPT. Two MPPT circuits were implemented with a temperature based constant voltage algorithm to prove size constraints and power sharing capabilities. The results of this project have produced a working analog MPPT and microprocessor firmware able to provide telemetry data to the Fox-2 Internal Housekeeping Unit (IHU) based on the Fox-1 standards.
The MPPT circuit developed for AMSAT successfully tracks the maximum power point based on temperature of the solar panels. The analog MPPT algorithm implemented suggests an improved robustness over microcontroller-based MPPT algorithms investigated. The power handling capability of the MPPT can easily be increased by sourcing higher power components, providing AMSAT with a very useful and scalable design. A great deal of effort was put into making the PCB easy to use and accessible for testing with numerous test points. The delivered hardware has been accompanied by a large amount of analysis and documentation compiled by the P13271 team members.
