lcl滤波并网
说明: 并网逆变器通常采用L滤波器,虽然结构和控制简单,但是随着功率级别的增加会地带来体积重量增大等问题。LCL滤波器适用于功率较大的场合。(Grid-connected inverters usually use L filters. Although the structure and control are simple, problems such as volume and weight increase with the increase of power level. The LCL filter is suitable for occasions with large power.)

三相三电平逆变器的两个相同电路进行建模power_3level
说明: 该模型是对50kW、380V、50Hz三相三电平逆变器的两个相同电路进行建模。IGBT逆变器采用SPWM技术,(8kHz载频)将直流电源从a +/-200Vdc源转换为220V AC, 50Hz。逆变器通过75kVA 220/380V变压器输入50kW电阻负载。变频器输出采用L-C滤波器滤除主要产生于8kHz开关频率倍数(Fh=n*8000 +/-k*50Hz)附近的谐波频率Fh。逆变器所需的12个逆变脉冲由PWM发生器块产生。该系统以恒定的调制指标在开环中工作。
电路1使用三电平桥块对逆变器进行建模。电路2使用独立的IGBTs和二极管块。用开/关延时块模拟死区,仅在电路1上应用。(It is easy for us)
