基于lc滤波器的pwm逆变器虚拟同步机控制(Inverter synchronizer control)

单相逆变并网电路的主电路与控制电路的 simulink 拓扑结构图， 主电路由直流源、 mosfet 全桥、 LC 无源滤波器、 负载 R1、 R2 组成， 其中 R1 为 恒定负载， R2 为仿真负载突变并入的。 控制电路为 SPWM 闭环调制， 通过检测输出端的电压有效值通过 PI 控制器反 馈回控制端使输出电压尽可能为一个优质的正弦波且有效值在 220V 左右， 频率 为 50Hz， 根据相关准则输出电压波形 THD 应在 5%以内。(The Simulink topology of the main circuit and the control circuit of the single-phase inverter grid connected circuit, The main circuit is composed of DC source, MOSFET full bridge, LC passive filter, load R1 and R2, wherein R1 is The constant load, R2, is incorporated into the simulation load mutation. The control circuit is SPWM closed loop modulation, and the effective value of the output voltage is detected through the PI controller The feed back control makes the output voltage as high as possible a sine wave, and the effective value is about 220V, frequency For 50Hz, the output voltage waveform THD shall be within 5%, according to the relevant guidelines.)
