    In this video I will be conducting a couple tests with a transformer in order to not only explain how it works, but also how to design one by yourself. We will be talking about mains voltage transformer and SMPS transformers and we will find out (for example) how the size and frequency of the voltage alters the design of the transformer. At the end I will then answer the question whether it is easy to create a transformer on your own. Let's get started!

    I want to build a few of these for DC battery bank stick welding. Different types for different tasks. Car batteries have up to 600 cold cranking amps at 14v. How big would one of these end up being?

    This video is so awesome.
    At my work we built a couple of Three-Phase transformers that were designed to transform 110VAC to 50VAC at 125Hz. We were struggling with saturation and we had to adjust the design of our system, thus increasing the operating frequency from 125Hz to 250Hz (not such a big deal since we were going to use a three-phase rectifier for those phase-phase voltages)
    This video was very educative.

    Can you please make a video explaining Generators or Alternators? That would be so awesome

    Voltage drop due to inductance and back emf both due to one and the same reason..their values should be the same.

    Why are those ultra small transformers that they place in preamps and microphones sometimes cost up to 400 dollars a piece? Is it marketing or is there something extraordinary about the production process?

      @Adithya angara I think you right sir. But sir can you make a video on this topic.....how to convert 3.7v DC to 400000..V AC voltage 😊😊😊😊😊please sir i request you 😅😅😅😅😅

    • Adithya angara
      Adithya angara 2 months ago +1

      bruh wrong unit, you can't convert Volts to Watts. If you mean volts either side. you're looking at a conversion of 3.7v to 400000000 V. That kinda voltage will be able to jump 134 meters approx. thats like 0.15 km. I don't think you'd wanna create such a device even if you could. The ionization of gases in the 0.1km could easily make you lose consciousness if the current doesn't. Ah well theoretically anyways, a 134m spark gap is ridiculous.

  • david sdavids
    david sdavids 2 months ago

    good work. after six minutes, i offer the following info. any 'conventionally wound',
    multi-layer coil has an ISSUE. the issue is a MEANDERING current Path.
    this Meandering current path is a Key factor in the performance of Self-inductors/generating coils.
    at other times, the resultant back-emf/fields 'works against' the creation of maximum flux
    density, in core material. this issue derives from the way in which coils are usually wound.
    a meandering current path is created, and, the current flow in Adjacent coil Layers is
    out of phase; 180 mechanical degrees. this condition is the source of back-emf, and
    associated impedance. is this information represented in the math, somewhere;
    is it in copper losses. cheers

    I enjoy watching videos. I was also searching through internet to how to calculate winding turns. There were various formulas and calculators. But values they giving does not match nearly for transformers we saw in old televisions and ups transformers. Hope you can do a video about how to calculate number of turns and core area for specific power of transformer.

    So the high resistance on the primary coil is to limit the current so the primary windings wiring doesn’t melt? Is this correct?

    Transformers are like electrical gears. Or levers.

    I always wondered about this. I once tried to build a transformer out of a nail and some enamel coated wired. Except the wire was only 0.2mm diameter and the lowest voltage transformer I had was 16v. I apparently forgot that joule heating was a thing and the enamel coating melted and the primary winding shorted. Guess I could try again with a resistor to limit the current. They have really bad hysteresis, but for some reason I love the idea of making a transformer or inductor out of a nail.
    I even tried making an RC oscillator with a nail and enamel wire for the inductor and a capacitor I made by sandwiching a piece of plastic wrap between 2 sheets of aluminium foil and folding it up to take up less space. But unfortunately the capacitor was too leaky to be any use. But I was able to measure a capacitance of around 500nf. Rimstar is a good channel to browse for stuff on making your own capacitors.

    This truly shows that with transformers, there's more than meets the eye.

  • Melkior Wiseman
    Melkior Wiseman 2 months ago +1

    Short version: The principle is simple. Putting it into practice isn't so simple, especially if you need a particular voltage and current.
    Basics: More turns of wire on the secondary than on the primary equals a voltage step-up with a reduction in abilty to supply current. The opposite is also true. And that's only the beginning.

    really complex formulas that took some people years to figure out, all brought into one video. and broken down so my dumb ass can actually understand it... thanks this is exactly what i needed. I have a transformer calculation app on my computer but it is really hard to use and doesn't explain the formulas....this was so good..and they thought i was never gonna need algebra again..lol
