Hi @Power_Control 

Thanks for posting on the Infineon Community page.

For selecting  an IPM module follow the below points:

1) Select the voltage rating at least 1.5 times of DC link voltage

2) Select the current rating at least  2 times the rated current.

3) Fix the switching frequency.

4) Calculate the loss and find the junction temperature rise.

I would like to suggest two IPMS from Infineon which suit your application
