초록
In this paper, two configurations of PV array are analyzed and tested under shading condition, where two configurations are series-parallel and total-cross-tied configuration. Each photovoltaic module is emulated by two 5 inch poly-crystalline cells in series and an array is constructed by connecting 24 of the modules to compare a generated maximum power of the two configurations. Pspice and Sun simulator, PASAN Ⅲb, are used for simulation and experiment to test the array under various partial shading conditions. Test results show the total-cross-tied configuration generates 7.63% higher maximum power than the series-parallel configuration, and it is well matched to the analysis and simulations of the two configurations.
