    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?

    Powering Multiple DC Devices

    I want to apologize for having my first post be so long. Since I am not sure where to start, I thought it might be beneficial to explain the whole problem I am designing/building a fly pack for my video gear. The pack is built in an 8U - 15” deep case that contains a number of Blackmagic Design...

    Calculate power

    Hello, considering a sinusoidal voltage source and a half-wave doubler rectification (as in the picture), how is it possible to calculate the DC power on a resistor R when considering ideal diodes?
