Abstract :
Because of the effect of weather and environment on photovoltaic (PV) array, it is hard to perform all round tests on equipment of pv generation system with the real PV array as test. So a novel pv array emulator system based on Zero-Voltage Zero-current Full-bridge converter with two diodes in series with lagging leg is put forward and a mathematical model of PV array, which use a linear model formed by the two lines, been adopted to make the control of the emulator simple convenient and reliable. In order to confirm the effectiveness of the system, the model of emulator system was established by Matlab Simulink. The result show the pv array emulator system realize to behave electrically similar to real PV array.
