MOSFET (Si/SiC) Forum Discussions

Hi team,

We recently come across  Infineon power simulation .

Our requirement is to simulate a BLDC driver H bridge circuit  , Actually MOSFET 's are not  available in the tools , only IGBT's and Modules found .

Our FET Part no's are below 

1.IRFP7530PbF

2.IPTC014N08NM5

Can you please help us to simulate above FET's or even equivalent to them   for power and thermal calculations 

40H register of tle9183qk，called om_over:

bit 7 norm_m:normal operation mode(motor driving mode )active

bit 6 rect_m:normal operation mode(rectification mode )active

here is my question
① how to understand motor driving mode and rectification mode?

②Under what conditions will tle9183qk enter the  motor driving mode and rectification mode?

I am trying to understand how to import an ISC0602NLS model into LTspice.  There is a file called: OptiMOS5_80V_LTSpice which contains the power FET in question when I go to the product page and download the spice simulation files.  Normally the models I have imported in the past have only 1 component and I build it by creating a component from subcircuit.  How would I go about importing and using this model?  I attached the relevant file.

Thanks for the help.

What is the footprint of F415MR12W2M1B76?

1 :Pin assignment above G2 and S2

2:Pin assignments under DC1-

3:All pin assignments around DC+ are DC+?

4:Pin assignments under DC2-

5:Pin assignment above G4 and S4

6:All pin assignments around AC1 are AC1?

7:All pin assignments around AC2 are AC2?

Best regards.

The output waveform of my inverter is like this (yellow curve):

I assume this has something to do with the DC bus, for I didn't add any bus capacitance. After adding one 220uF electrolytic capacitor and one 100nF capacitor, the waveform became like this:

It seems to be better, but the voltage spike is still large. I wonder if this phenomenon is normal ? If not, what can I do to improve the output waveform of my inverter. I tried to increase the gate resistor from 5.1Ohms to 50Ohms, but it would't help to better the waveform and only to decrease the switching speed.

PS: the gate driver schematic diagrams is presented as below.

Good Morning, 

Can we please get the values of Drain, Source and Gate Inductances of the following SiC MOSFETs :

IMW120R220M1H

AIMW120R035M1H

Can you tell me where I can see if your components are washable?

I needed this information especially for the "IMBG120R090M1H".

Thank you in advance
