Hi everyone!
I searched this forum but could not find what I'm looking for, so maybe someone here could help me. I'm trying to find a replacement high voltage transformer for an electric fencer. The original transformer is a basic iron-core transformer with a primary winding of heavy wire with a relatively small number of turns, and a secondary winding of about a zillion turns of hair-fine wire. The transformer arced internally and developed a permanant short, so I'd like to replace it rather than buying a brand new fencer. The original transformer is rated at 10KV output. It put out a narrow pulse about once per second. The circuit is a very basic SCR capacitor discharge circuit that drives the transformer. My question is, how can I calculate the output voltage pulse of any given transformer if the turns ratio is known, and also if the value of the capacitor and its discharge voltage are known? Or do you need to know other parameters such as the inductance of the primary and secondary windings, etc? Does it get more complicated than that?
Thanks!
