Hello everyone:

           How to sample the current for the igbt FF400R07A01E3? Is it necessary to increase the sampling resistance?

What is the conversion relationship between the collected voltage and current? Is there any literature for reference?

          另外,需要用英语问问题吗?

Miaoxianshen,

您好,您可以在FF400R07A01E3的驱动器(1EDI2010AS)的Datasheet117页找到应用举例。

针对转换比率。Ic=800A,Rsense=1.6ohm,Vsense是0.64V--这意味着通过辅助电流感应终端的电流应该是=0.64/1.6=0.4A。因此,Isense与Ic的比例为1:2000。

如果您需要更详细的设计信息支持,请联系您当地的英飞凌办公室或者代理商。
