The Intelligent System Of Space Power Sources

Space power sources system is one of the most important parts in space , supplying power to all kinds of sub systems of the space in different flying period. The power required to supply is more and more along with the rapid growth of space utilization. Besides the power requirement, the service period of a satellite has been expanded from days to years or even tens of years, all of which required the power supply system more mass-power availabe, more efficient and more reliable.Taking advantange of this opportunity, the performance of the power supply system is becoming more important. In order to improve its performance, this thesis adopted an internationally famous power supply control system topology sructure-S4R (The sequential switching shunt series regulator) and combined three different control methods to make a digital integration of the power control system, which realized control of the highly efficient and intelligent discharge of the storage battery allies on the basis of smooth power supply.
