一种SPWM激励下卷铁芯电磁-结构耦合振动改进模型

The modeling and analysis of transformer core electromagnetic vibration considering hysteresis and magnetostrictive effects are challenging multiphysical problems. For SPWM application scenarios, a new vibration-predicting method of the wound core based on electromagnetic-structural coupling model is presented. First, the magnetostriction neural network model based on time-domain characteristics (...
