While it isn’t exactly certain which path technology will take as it continues to advance at a break-neck pace, there are two traits that can be found in practically every device nowadays that don’t seem to be going away any time soon, namely the screens keep getting bigger and the components smaller. The bigger screens aren’t exactly a necessity and in fact some people don’t really like staring at a monitor so ridiculously big and bright that it could stand in for the sun. However, the reduced size of most technological components is in contrast quite useful as that means parts like the regular larger transformer can easily be replaced with a toroidal transformer which takes up much less space and performs its given task even better.
The toroidal transformer is a device that uses circular magnetic cores or ferromagnetic materials like iron powder, ferrite or laminated iron around which wire is wound. This shape results in this particular type of transformer being more efficient than any standard models as the magnetic flux that escapes outside of the core is low thanks to the symmetry of the design.
The transformer is comprised of a core, as well as a primary and secondary coil of wire. Electricity passes through the primary coil and builds a positive magnetic field that increases to a peak and then collapses as the voltage decreases to zero in the first half of the cycle. In the second half, the current builds a negative field because the electricity is passing through in the opposite direction, and the field collapses again as the voltage returns to zero. As the positive and negative magnetic fields build and collapse, they pass through a second coil of wire wrapped around the same core, and as they pass through, they generate the output voltage.
A toroidal transformer is a crucial component in the toroidal voltage converter, which is a device that changes the voltage of an electrical power source. The advantages of the toroidal transformer play a vital role when the temperature rises during normal running, and is being dissipated with relative ease thanks to the characteristics of the material itself. The fact that it makes normal running temperatures possible aside, it also makes for higher conversion efficiency (its smaller size and it not producing virtually any noise or interference).
Even though many people haven’t even heard of what a toroidal transformer is, it is a very significant component in a lot of the major everyday appliances that a large part of the population has in their homes.
