usermat_CDM
说明: These composite materials generally exhibit brittle damage behavior. The anisotropy in the
material and different kinds of failure mechanisms make it difficult to accurately
characterize the behavior of composite materials. The present work aims to verify and
apply the Puck Failure Criteria using the commercially available finite element package
ANSYS by writing a user-material subroutine in FORTRAN. The model is implemented
with different post failure degradation schemes EWM/CSE.

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)
