Sizing AC power supplies

  1. Sep 8, 2011 #1
    I plan on using a very large solenoid for a magnetic field experiment. I have estimated what I believe to be the inductance and resistance of the solenoid and, with the desired field to be produced, almost 20 amps will be required.

    After running a simple simulation, I am not sure how to select the right size of an AC power source. Vendors have them rated by kVA or kW. But do I need to choose one based on the peak value of the sinusoidal waveform or some other measure?

    Welcome to the PF.

    What frequency will you be using in this experiment? Can you post links to some typical power supplies that you are considering?
