Hello, when I use PLECS to simulate IGBT model, I downloaded the FF450R12ME4 PLECS thermal model from the official website, and imported it into PLECS software to simulate and found that the loss is consistent with the IPOSIM online simulation, but I used PLECS to build the thermal model according to the datasheet and found that there is a big difference in the simulated loss, comparing the officially downloaded thermal model with the datasheet, I found that not switching loss is consistent, and the simulated loss is very different, which completely loses the meaning of loss assessment. I found that the loss of the simulation is very different from that of the datasheet, which is not the same as the loss of the switch, and the significance of the loss evaluation is completely lost, and the data of the thermal model downloaded from the official website is higher than that of the datasheet. The picture is the comparison between the thermal model data downloaded from the official website and the datasheet. The datasheet usually only shows 125 degrees and 150 degrees, but the official model shows the loss at 25 degrees, 50 degrees, 75 degrees and 100 degrees, how can I get these data? Thank you, and I look forward to hearing from you!

The easy2b packaged material is difficult to mount and often suffers from thermal failure due to poor mounting, do you have any suggestions? Or do you know of any user feedback?

Fans in the knowhoo question, please engineer answer ~ thank you!😀

As the question, please ask the engineer to answer in detail, can be accompanied by a graphic, but also hope to introduce some Infineon products. Thanks for your help.😀

Hello, SSD's floating gate transistors are structurally damaged in the tunnelling layer after a lot of tunnelling writes, how can I design a chip that can automatically repair similar structural damage like biological tissues?

Can the engineer elaborate on the methodology of designing such a chip, talk about his/her opinion, and recommend relevant Infineon products?

Grateful for that!😀

Difference in performance between high voltage DC relays and IGBT switches, and is there any possibility of replacing DC relays with IGBTs?

I want to do IGBT Characteristic curve fitting by IGBT tool of saber, but I can't find the capactior (cre, cie, coe) data curve in the data book of FF50R12RT4. There are just two specific values of cie and cre. This makes me not know how to model IGBT concretely
