In this article, the power generation of a concentrated space solar power station (SSPS) is enhanced by current-injected total-cross-tied (TCT-CI) photovoltaic (PV) array. First, a mathematical model of the TCT-CI–connected PV array is established. Second, PV arrays with several common topologies and TCT-CI topology are simulated and analyzed using MATLAB/Simulink. At last, comparative experiments are conducted for TCT and TCT-CI–connected PV arrays under the condition of non-uniform light intensity distribution. The results of the above indicate the following: 1) TCT-CI–connected PV arrays reduce the difficulty of MPPT in concentrated SSPS, 2) TCT-CI–connected PV arrays increase the power generated in concentrated SSPS, and 3) TCT-CI–connected PV arrays are applicable for concentrated SSPS.
