Selecting the Right Size AC Power Supply for a Large Solenoid Experiment

AI Thread Summary
Selecting the appropriate AC power supply for a large solenoid experiment requires understanding the solenoid's inductance, resistance, and the desired current of nearly 20 amps. The power supply ratings are typically in kVA or kW, but clarity is needed on whether to base the selection on peak values of the sinusoidal waveform or other metrics. The frequency of operation is also a critical factor in determining the right power supply. Additional information on potential power supplies being considered would aid in making a more informed decision. Proper selection is essential for achieving the desired magnetic field effectively.

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?

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
