Overview of Topology Inference and Optimization Methods for Spacecraft Multi-port PCU
PCU(power control unit)needs to control power between input port,energy storage port and output port.With the addition of more different types of energy interfaces,multi-port converter with high power density,high efficiency and other high performances becomes the ideal solution for PCU.The topology of multi-port converter is an important foundation for the imple-mentation of spacecraft power supply and distribution function.Focusing on the circuit topology application and mission requirements of spacecraft multi-port PCUs,the investigation and sum-mary of various topology inference methods and main topology performance optimization methods are conducted in the paper.On this basis,key development directions for the topology design are proposed,such as normalized topology inference process,complete topology performance optimi-zation method and PCU design idea based on the overall level.The research results presented can be as a reference for further space exploration,larger scale power supply and distribution system construction and new energy management design in space missions.
