CRD25DA12N-FMC as a three phase power supply

Dear Experts,

I would like to use CRD25DA12N-FMC as a three phase DC to AC power supply up to 10kW max.

My questions are:

  • Do you have a firmware that support off-grid mode of this power supply maybe with active power control?
  • In the PCB there is no null output just the three phases. How can we achieve that?

Thanks and regards,

Andras Magyar

    Hello Andras,

    Thank you for your interest in this product. We have firmware that supports sine pulse width modulation (SPWM) open-loop control. This firmware can be modified to fit the end application needs. The firmware is available for download from the webpage for this design. Regarding the null, this design has been tested with line-to-neutral loads with a floating neutral, so a null connection was not necessary on the board.

    Thanks,
    Chris N.
