TIDA-00366: lower battery voltage to 84 VDC and using MOSFETS instead of IGBT

Part Number: TIDA-00366
Other Parts Discussed in Thread: TIDA-00364,

Hello, the TIDA-00366 Reference Design for Reinforced Isolation 3-Phase Inverter is very promising when comparing to another design (TIDA-00364) which we also consider for our application.  But now we use 84 VDC battery (74VDC nominal) and MOSFETS - what should be changed in UCC 21520 conditioning and in power stage ?

I know about changes needed in current and voltage sensing - both areas will be changed but the power stage is concern. I want to use power MOSFETS parallel circuit from TIDA-00364 instead of IGBT module.

If it is doable please let me know.

Thanks in advance

Vladimir
