“Open” A waveform will appear
showing what happens when a step is delivered to an inductor. It is a falling
exponential. At the top of the graph,
find the list of words “File Settings
Voltages …. View” Click on “View”
Click on “Pulse”
You will now see the
waveform when a pulse is delivered to an inductor. Click on “Settings”
Click on “Parameters” Under “Simulations
settings”, reduce “Number of iterations” to 100. Click on “OK” You will see that what appeared to be an exponential was really a series of small steps. The waveform only appears to be an exponential if the width of the inductor is small compared with the rise time of the inputted pulse. Here you have the smoking
gun; the proof that an inductor is a transmission line. To
continue. Click on “Settings”
Click on “Parameters” Click on small window
“Transformer” Click on “OK” We now have a pulse
delivered into a transformer. Click on “View”
Click on “Sine” We now have a sine wave
delivered into a transformer. Click on “Settings”
Click on “Parameters” Reduce the number of iterations to 30
Click on “OK” We begin to see that the inputted sine wave, and the output, can be seen to be a series of steps. Ivor Catt 12sep02

The London IEE rejected for publication the working out of the detail for the transformer as a transmission line. This was at the same time as the IEEE accepted for publication the working out of the detail for the two turn inductor as a transmission line, see ProcIEEE June 1987 reproduced at http://www.ivorcatt.com/4_6.htm . The two processes are very similar. See http://www.gibsonridgesoftware.com/physics/two_turn_inductor/tti_derivation.htm . This analysis of the transformer has never been published, and the idea that, like an inductor, a transformer is a transmission line, is not known. Acceptance for publication by the IEEE of the two turn inductor is an exception. Generally, all learned institutions [including the IEEE], and all of academia worldwide, and all text book writers, have taken a blocking position over all of this material, which is the gateway to improved transformer design.

. Print it out. This gives definitions of the symbols, e.g. Zc . Now the various waveforms can be investigated more thoroughly. Caveat. You need the theory on crosstalk, see http://www.ivorcatt.com/4_1.htm |
