I just finished some changes to my website http://inductionheatertutorial.com

I was hoping that if anyone had some comments such as criticism, improvements, subtopics they would like to see, or if they are happy with its current form. The site goes into some theory. This is followed with some scope waveforms, and finally with a description of the circuit design. The unit can easily go over 10-12kw, and can boil copper and steel while levitating the workpiece.

Wow this looks nice!
 
Great tutorial,... I am working with up to 200KW units daily, but this little system is cute :smile:
 
When working with such high power levels, how do you handle the switching? Do you run several parallel IGBTs, or are there single units for handling such power?
 
The units I am working with are pretty old, from around 1985, there are two towers of 5 parallel SCR's. Interesting setup and amazingly it still works after more than 20 years of daily use!

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...
