A Hybrid SMC Strategy for Sequential Switching Shunt Regulator

This paper deals with the sequential switching shunt regulator (S3R) which widely used in high power GEO satellites owning to its high reliability and simplicity, however This regulation method has problems caused by its parasitic capacitance (C SA ) and conventional control methods. Here it is suggested a hybrid sliding mode control (SMC) strategy for S3R to improve the main bus voltage regulation along with lower current fluctuations. Additionally, an architecture is proposed for solar array sections to increase the reliability of the system and to achieve targets mentioned above. The performance of the proposed method is investigated by MATLAB/Simulink.
