PMP21516: Changing design to operate in three-phase + neutral

Part Number: PMP21516
Other Parts Discussed in Thread: PMP10344


I would to know if it's possible to change the initial stage of this design to use as a AC/DC three-phase+neutral input. 

I imagine that the initial stage of the circuit would be something like the PMP10344.

Best regards.


  • Hi Arion,

    It is certainly possible. You would need to take into account the rectified input voltage based on the AC input voltage and then make sure all of the ratings for the components are okay. Assuming that the input voltage is not too much higher, the transformer is probably okay, but if the input range changes significantly you would need to look at that as well.
