| 摘 要： | 在具有电感和电阻特性的弱电网条件下，研究滞环控制的并网逆变器稳定性问题。研究结果表明，过大的电感会导致并网电流出现跟踪松弛现象；过大的电阻会影响并网电流跟踪基准电流的幅值出现跟踪饱和现象。通过搭建一台5kW原理试验样机。试验结果验证了理论分析的正确性。

| Abstract: | The stability problem of inverter based on hysteretic control was studied in weak grid conditions with inductance and resistance characteristics. The research results show that a large inductance will cause the phenomenon of grid current tracking relaxation and a large resistance may lead to tracking saturation. Finally, a 5 kW prototype was build. The experimental results verify the correctness of theoretical analysis. |
