IGBT Forum Discussions

I recently purchased HybridKit Sense for MCU development.
While following the manual, I found out that the version of OneEye on the USB included in the package was 1.0 and that the configuration file was missing. I looked up this community and found out that Toolbox needs to be searched for the latest files, and I need that permission.
My email address is jgpark@evnsolution.com.
Additionally, is it possible to grant permission to leehangual@evnsolution.com and initusnovus@evnsolution.com as well?

Hello,

We are using FP35R12KT4 along with gate driver 1ed020i12-f2, with all desat protection in one of our VFD projects.

We are observing that on some of the site, there are failure in the devices and major cases Wbottom IGBT is getting damaged.

Attaching the images.- IGBT module in open view- highlighted the damaged part.

The schematic is also being attached.

Rg ON value is 39 Ohms and Rg off is effectively half of 39 Ohms i.e. 19.5 Ohms.

The gate drive is with unipolar supply of 15V as we are using active miller clamp.

Is this the issue of soft turn off or soft turn off  gate driver can be useful here?

Attached IGBT damaged pic, always W-bottom IGBT is always getting damaged.

Awaiting your reply!

Regards,

Mukesh

I want to use the half bridge switches to charge and discharge a battery with square charge and discharge pulses upon command.  I attached a simple diagram. . 

空穴的迁移率比电子的迁移率低，这是造成IGBT拖尾电流的本质？可以这么理解吗？

Dear all,

I hope you are doing well.

I want to know how I can calculate total thermal resistance(6 diodes with 6 iGBTs , take them in parallel or series) for the IPM IGBT Module without a heatsink.

Thanks
