About Power Supplies and Load Banks for Testing CRD-22AD12N

Sandun

Dear Wolfspeed,

Would it possible for you to share what power supply and load bank you use to test CRD-22AD12N 22kW in three phase inverter mode?

Thank you,

Hello Sandun,

The CRD-22AD12N operates in 3-phase rectifier (charging) mode, or single-phase inverter mode. The firmware does not support 3-phase inverter operation, but it is possible from a hardware standpoint if you develop alternative firmware. For testing this unit and many of our other reference designs, here is some of the equipment that we have had good success with as examples:

DC Power Supplies: Magna Power TSD series such as TSD800-54 and TSD1500-19.8, or Elektro-Automatik EA-PS 81000-30

DC Electronic Loads: Elektro-Automatik EA-ELR 11500-60

AC Source: Ainuo ANFS030A

Please let me know if you have any additional questions.

Thanks,

Adam
