Solar Direct-drive Integrated Anode Power Supply Conversion Circuit

The anode power supply is the main power module of the Hall thruster, and as its power continues to increase, the use of direct PV drive can achieve decoupling of the anode power supply from the platform bus, so the integrated design of "S
³
MPR+DC/DC" is used. The solar array as input and ionized gas as load, both with certain instability, can lead to more complex working conditions of the integrated anode power supply, thus putting special requirements on the adaptability of the integrated anode power supply. In this paper, the circuit structure and operating mode of Hall thruster integrated anode power supply are analyzed, and the main power circuit and integrated control strategy are designed. Based on the theoretical analysis, the circuit is simulated with MATLAB software, and the simulation results verify the correctness of the theory and design.
