3 Phase 2 Level AFE 22kW vs 25 kW Design. Which one's better in cost/efficiency/implementation?

Udit

I am eagerly looking forward to design, build hardware and test a 3 Phase 2 Level AFE converter at 20kW, 480VAC input and more than 800VDC output.

Wolfspeed has 2 designs "

CRD-22AD12N - 22kW using SiC MOSFETs" and "CRD25AD12N-FMC - 25kW using SiC module". I am having a hard time comparing these two designs as there is not much documentation available. In terms of comparison I am looking at cost involved, efficiency and ease of implementing the whole design.

Any sort of help is highly appreciated!

Thank you.

Hi Udit - thank you for posting. This is a great question and I dont believe that we have a crisp summary to share. One of our applications experts is looking into creating one so please stay tuned.
