IGBT逆变器采用SPWM技术power_3level
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)

ABAQUS技巧积累
abaqus 使用技巧-Inp文件中单元类型改变时，一定要注意，划分网格的时候是否，选用了一种望各类型，比如4变形和3变形的区别，如果用注意将所有的单元类型都做相应的修改。这说明单元类型由2个因素决定，1网格形状，2计算任务.(Abaqus tips-When changing the unit type in the Inp file, be sure to pay attention to whether or not to select a type, such as 4 deformation and 3 deformation, if you use the attention, all the unit types should be modified accordingly. This shows that the unit type is determined by two factors, 1 grid shape, 2 calculation tasks.)
