ac /dc power supply calculation

[jr__alvarez]

I've been asked to design a power supply ac/dc with the following parameters:
3-phase input 208VAC @ 60Hz
3-phase output 72VDC @ 60ADC

and I've alson been asked to consider a low line of 177V.

Can somebody help me on this and if so what other issues do I have to consider: like voltage regulators and capacitor bank, etc....

I would appreciate any info , thanks.

Good luck on this one.

I understand how you might be confused with 3-phase DC output, no such thing. All the other specs are easy with switch mode rectifiers.
