摘要
在研究并网逆变器基本原理的基础上,设计了基于无差拍控制的并网逆变器。阐述了采用无差拍控制技术实现并网电流对市电电压的跟踪和参考电流信号的控制,同时给出了基于TMS320LF2407A的系统软件设计程序流程图,并进行了样机实验。实验结果表明,该控制策略简单、有效,系统的并网电流波形较好。
On the basis of researching basic principle of grid-connected inverter, grid-connected inverter was designed based on deadbeat control. The realization of grid-connected current tracking net voltage using deadbeat control and the control of reference current were presented. Simultaneously, the program flow chart of the system based on TMS320LF2407A was proposed. Sample experiments have been done and the results show that the control stratregy is simple and effective, and the wave of grid-connected current is better.
