  • Experiment to show that balun heating is due to common mode voltage. It's a good day when experimental and simulated results match!

    I'm going through each of the videos and watching them on my TV.
    Thank you for making this video Larry! I am of course subscribed with notifications turned on and thumbs up! 73 W3GUY

    An interesting experiment. Maybe a dumb question: is there a practical application?

      Dragan,
      This circuit could act as a 180 degree phase shifter when compared to a piece of transmission line of equal delay. What I wanted was a way to separate the heating effects of the differential and common mode currents and this circuit does that well and it is easy to reproduce. I think you have been watching my channel long enough to know that I really like when the topics I discuss can be experimented on by the viewers easily. We really live in a wonderful time as electronic and RF test equipment is reasonably priced along with cheap fast computing. Add in free simulation software and about you need to understand RF is the desire to do so. Some of the circuits that I demo in SimSmith have millions of calculations taking place as components are swept and you can see the results in real time. Maybe I'm just easily impressed but I would have loved to have had these capabilities when I was a kid. :)

      Anyone that had to click that run button in LTSpice, more than a few times, is impressed by SimSmith ;) Not to mention that it's a wonderful learning tool. I wanted to replicate this experiment with a TV yoke ferrite but then I realized that I'm not sure what it would actually mean. Just shows that I need to learn more about the topic.

    Pictures don't cut it. You need to provide schematics for us to know what you are trying to do. You end up spending a lot of time explaining your pictures because you have no schematics. Your pictures in Sim Smith don't work well either. All of this can be very confusing.

      Sorry you feel this way. I intend to do more on balun heating and will keep you comments in mind.
