粉丝在英飞凌知乎发的这篇文章问了这个问题：为什么不直接根据测试数据积分呢，还要分段线性拟合

Hello,

I am building a high voltage inverter operating at 200v. i am using isolated gate drivers and the supply for the gate drivers (15V) is also isolated. But the inverter switching causes a voltage spike in the gate driver power supply . the spike is happening at 40khz which is twice the switching frequency of the inverter. I have dc link capacitors and mlcc filtercaps attached to the dc line

Can someone help me figure out why the inverter switching noise is propagating to the low voltage side.

Thank you

Hi all,

Please let me know the meaning of red circle and blue circle.

CE间电压随着集电极电流上升而线性上升，这个区域称为饱和区

线性增加，那不应该叫做线性区吗？

到了所谓的退饱和区，电流饱和了啊，反而不叫饱和区了，这不是很奇怪吗？

你们是怎么定义饱和这个概念的？

The IGW75N65H5_L2 Spice model does not function in LTSPICE, giving the error "Unknown subcircuit called in: xu4 n030 n033 n034 igw75n65h5_l2 tj=27"

The application notes (https://www.infineon.com/dgdl/Infineon-AN_2020_17_Simulation_models_of_IGBTs_and_power_silicon_diodes-ApplicationNotes-v01_02-EN.pdf) for this spice model seems to suggest it is compatible with LTSPICE.

Any help would be appreciated.

Can you help me see if this is normal? Is this pin condition caused by the electroplating process? Or was it renovated?

Bonjour,

je souhaiterais savoir si le  IHW30N160R5 est un bon équivalent du IHW30N160R2 ?

Hi all, 

是否现在IPM 仿真软件都无法使用？

无法进入到详细参数输入界面。

IKQ150N65EH7中计算Ic vs. Tc曲线，根据Explanation of discrete IGBTs' datasheets第五页上面的公式：

175-125=0.24*Ic*1.6，Ic=130A，与曲线对应不上。
