Highly Reliable Reconfigurable Power Supply Technology for Spacecraft

Power system technology is one of the key technologies of spacecraft, and the performance of power system has an important influence on whether the spacecraft can fly normally and achieve its scheduled tasks. Aiming at the demand of spacecraft for highly reliable power supply, this project proposes a module circuit topology dimension reduction and reconstruction technology to improve the reliability of power supply system. The power supply module adopts an online reconfigurable parallel structure to improve the power output capacity, so as to increase the redundancy of the power supply of the power module and ensure that the power supply system can still maintain the normal power supply capacity under the condition that some functions of the power supply module are damaged; The on-line reconfigurable three-degree-of-freedom circuit topology is adopted to broaden the working range.
