| 摘 要： | 本文根据光伏并网系统的特点和光伏系统对并网逆变器的要求设计了一种新型的并网逆变器。本逆变器不仅控制输出交流电流,而且增加了直流侧的稳定电压的控制,使逆变器的输出功率因数为1。本文从理论上详细的分析了控制方案的可行性,并在理论分析的基础上给出了基于SVPWM矢量控制的MATLAB仿真结果,验证了系统的稳定性和可靠性,并能显著的改善并网逆变器的性能。

| Abstract: | This paper designed a new type of Grid-connected inverter based on the photovoltaic characteristics of grid systems and the requirements of Grid-connected inverter. The inverter can not only control the output AC current, but also increased the stability of DC side voltage control to ensure that the inverter output power factor is 1.This paper detailed the feasibility of the design in theory, and gave vector control simulation results based on SVPWM theoretically, confirming the stability and reliability of... |
