In DC micro-network experiments, the photovoltaic cells are essential, however, it is necessary to develop digital photovoltaic simulator because of the laying area and uncertain output of the photovoltaic cells. A photovoltaic cell simulation model is established based on the equivalent circuit model by combining with the block of Simulink. According to the model′s output characteristics, a Buck chopper controlled by DSP 28335 is designed to achieve the output of photovoltaic properties. The design of main circuit and detection protection circuit are given, several algorithms of photovoltaic tracking are analyzed. Finally, the photovoltaic simulator output characteristic curve and output waveform of different algorithms are also put forward.
