基于DSP的智能光伏并网逆变器控制电路设计
资料介绍
目前分布式光伏并网发电已开始越来越普及，因此设计智能、高效、可靠的小型光伏并网逆变器具有十分重要的现实意义。根据光伏并网发电系统特点，研制了一台2kW的单相光伏并网逆变器，该逆变器采用成熟的主电路结构，以数字信号处理器（DSP）为主控芯片，分模块设计了控制电路，实现了最大功率点跟踪（MPPT）控制、双闭环并网逆变控制、数字锁相环（DPLL）控制等功能。样机经现场运行，结果表明所设计的控制电路可行，控制效果理想。
Currently small distributed photovolaic（PV） grid-connected power is becoming increasingly popular, so the design of intelligent, efficient and reliable small PV grid-connected inverter has very important practical significance.Ac- cording to the characteristics of the PV grid-connected power system, a 2 kW single-phase PV grid-connected inverter is developed,the inverter main circuit uses sophisticated structure of digital signal processor（DSP） control chip,sub- module design of control circuit, the MPPT control, double-loop and inverter control, DPLL control and other control functions, prototype running results show that the design of the control circuit feasible control and results are satisfactory.
