Fixed Switching String Shunt Regulator (FS3R) – A Novel Solar Array Regulator (SAR) Concept

This paper discusses the novel Solar Array Regulator (SAR) concept which solves the issues arising due to the parasitic capacitance of Ga-As based triple junction solar cells with a larger area. The proposed Fixed Switching String Shunt Regulator (FS
³
R) concept helps improve the performance of the SAR in comparison to the classic Sequential Switching Shunt Regulator (S
³
R) with respect to the double sectioning and dynamic performance. The improvements of the proposed SAR with respect to the modularity for scaling power handling capacity are also presented in this paper. Both simulation and hardware results are presented in this paper to validate the proposed FS
³
R concept.
