摘要
根据光伏并网发电系统的特点,设计了一套基于数字信号处理器TMS320F28027控制的单相光伏并网逆变器,分析了系统的结构和控制原理,并对系统的逆变输出和DSP输出SPWM波形进行测试。实验结果表明,并网电流波形良好,逆变器输出的电流基本与电网电压同频同相,并网的功率因数近似为1。
According to the characteristics of grid-connected photovoltaic system,the paper presents the design of a photovoltaic grid-connected inverter based on the digital signal processor TMS320F28027,and analyzes the formation and control principle of the system.The output waveforms of inverter and DSP output waveform are tested.The experimental results show the grid-connected current wave meets the need.The wave of grid-connected current has the same frequency and phase as the utility voltage.The grid-connected power factor approaches 1.
