Transformers are used to turn the voltage output up or down. For them, modern electrical engineering is impossible to imagine. A toroidal transformer is one of the most highly efficient. This reflects a core formed by a loop, interwoven with wire, and steel strips are rolled up inside.
Electricity flows through the winding core and produces magnetic fields. The magnetic field passes through the first winding in the coil to get the output voltage.
How it works
Like transformers of another type, the toroidal transformer has an ideal configuration. In reality, Faraday's first transformer had been a transformer on a toroidal heart.
Toroidal cores are made of steel with very low loss rates and high induction of saturation by a magnetic coil transformer. This is done by heating the toroidal frame to a high temperature and then, according to a special program, cooling it down.
It allows saturation to reach high degrees up to 16,000 Gauss. The magnetic flux is evenly distributed in a toroidal transformer in the middle, so due to the lack of intermediate metal parts and technical gaps.
When using toroidal transformers supplied with free twisted leads, up to 64 percent of the space occupied can be saved compared to conventional transformers with lined cores (it is also easier to connect equipment using the transformer leads rather than the terminal blocks).
toroidal (ring) core has an ideal shape which allows a transformer to be produced using a minimum amount of material. All windings are distributed symmetrically around the entire core circumference which significantly reduces the winding length.
This results in a decrease in winding resistance and an improvement in output. Lower magnetic induction is likely, as the magnetic current travels in the same direction as the core's silicon steel during rolling.
