    Hello.
    The question is mainly like in the topic - what are the differences between a transformer, a transformer, a transformer and a toroidal transformer?
    I know what a transformer is :) Isn't the transformer another name for a transformer? What are the differences between a toroidal transformer and an ordinary sheet metal transformer (ignoring the shape, of course).
    I would also be grateful if you could explain the difference (disadvantages, advantages, application area, interchangeability with each other?) Between a sheet-metal transformer and a toroidal one.
    Greetings!
    PS. I will thank you for each helpful answer with points; P.

    Trafo = transformer ;) A transformer is a high voltage transformer, e.g. in monitors or TV sets. The main difference between the toroid and the ordinary toroid is the smaller induction scattering, and thus it may have smaller dimensions than the usual one at the same power. Generally, toroids are better than "regular" ones, they can be used interchangeably, but as far as I know, toroids generate a larger current pulse when switching on the supply voltage - you have to give "free" fuses on the primary side.

    trafo is the same as a transformer ... only written in diminutive :)

    I remembered something else - toroids take less power in the idle state, they make less noise and have better cooling conditions ... In a word, a miracle, not a transformer ;)

    A toroidal transformer is not a miracle, because it is difficult to wind and rewind it.
    The second disadvantage is the price - in the store, the toroid is usually a bit more expensive than the regular transformer, and the toroids are sold much less frequently than the regular ones from the dismantling.
    Since toroidal transformers have a smaller stray field, they not only have better efficiency, but also create less distortion.

    it's just that the magnetic circuit in the toroid is closer to ideal ...
    the core of such a contraption is a rolled up strip of metal ...
    The design is more expensive because, as someone has already mentioned, we cannot wind the windings quickly and efficiently on such a core ...
    Each transformer generates a current pulse (surge) when it is turned on. And this is due to the commutation laws (the current on the coil cannot change abruptly ...). There are so-called transitional states ...

    I will put it briefly :)

    I saw a toroid composed of two arcs with bodies - but there was no mounting for these elements (the transformer was incomplete), and I did not see how it works.

Topic summary

The discussion clarifies the terminology surrounding transformers, specifically the distinction between "trafo" (a diminutive form of transformer) and standard transformers. It highlights that toroidal transformers are generally more efficient than traditional sheet metal transformers due to their smaller stray fields, lower idle power consumption, reduced noise, and better cooling conditions. However, they are more expensive and challenging to manufacture. Both types generate current pulses upon activation, but toroidal transformers may require more robust fuses due to larger inrush currents. The conversation emphasizes the advantages and disadvantages of each type, including their applications and interchangeability.
