摘要
介绍了一种在Z源逆变器输入电压发生变化时,通过对Z源电容电压的控制,快速稳定直流母线电压的PI控制策略.在详细分析了系统小信号模型的基础上提出了控制方法,同时设计了响应速度快,稳定性强的PI控制器.
With the technique to control capacitor voltage,a PI control strategy to keep DC-link voltage in Z-source inverter steady was presented.The control strategy was proposed on the analysis of small-signal model,and a fast- response and steady PI controller has been designed.
