    DC/DC Converter VS AC/DC Converter

    If you are using several different DC voltages inside a unit, (say 5v, 12v, 48v) ignoring efficiency, would it be better to use separate AC/DC power supplies for each voltage or use 1 AC/DC power supply for the highest DC voltage and step down the voltage with DC/DC converters from there?
