单相DC/AC逆变器大信号统一建模方法
Unified Large Signal Modeling Method for Single Phase DC/AC Inverters
基于并网及离网单相全桥逆变电路，本文提出并验证了包含控制及调制电路在内单相逆变器大信号模型统一建模方法。理论计算方法可以获得单相逆变器环路设计所需大信号数学模型，用于指导控制器设计；平均建模方法充分保留了原始电路结构(如桥臂中点及电路接地点等)，有助于充分观察内部电路和端口电压电流特征，尤其适合多变换器组合的系统级仿真。
Based on grid-tie and grid-off single phase full bridge inverter，a unified large signal modeling method for single phase dc/ac inverters is proposed in this paper. Large signal mathematical model for loop gain and controller design could be obtained with the proposed theoretic calculation method. The proposed averaging method preserves origin inverter circuit, such as branch middle point and ground point. It helps inner circuitry, terminal voltages and currents to be observed. Therefore, it is very suit for system simulation with multi converters.
