摘要： A method and system for implementing DMPP tracking of partially shaded/uniformly illuminated photovoltaic arrays using switched capacitor DC-DC converter is disclosed. Here, a dedicated SC converter is connected across each PV cell or PV module made of series connected PV cells wherein series connected modules make a PV string and parallel connected PV strings make up a PV array. This SC converter injects an equalization current across the PV module or PV cell so that the total current in the parallel combination of the PV module or PV cell and the corresponding SC converter is the same as the PV string current. In another implementation of DMPP tracking using SC converters, a dedicated SC converter is connected across each isolated PV module to perform MPP tracking of the respective PV module. Then all MPP tracking SC converter outputs are diode ORed to the common load.
