Toroidal transformer - its structure and advantages

There are several basic types of magnetic core for transformers - core, armor and toroidal. If we compare their functional characteristics and range of applications, then a clear advantage will be a toroidal transformer.

Such a device is characterized by the widest range of applications in very many branches of modern industry. Among the main areas in which such a device as a toroidal transformer is involved, it is necessary to name voltage stabilizers, lighting equipment, radio engineering, UPS (uninterruptible power supply), diagnostic equipment, medical equipment.

It should be said about the functional characteristics of devices of this type. A toroidal transformer is a single-phase power step-up or step-down transformer having a toroidal core with more than two windings. According to the principle of operation, it does not differ from models with rod or armor winding. Any transformer is, first of all, a device designed to convert electricity from one voltage value value to another. However, the features of the design of an electrical appliance such as a toroidal transformer, in terms of its core, can significantly reduce the weight and dimensions of an electrical machine. And, as a consequence, the technical and economic characteristics and indicators will increase.

It is a small volume and weight are one of the main features of such devices as toroidal transformers. Thanks to flexible free conclusions, the savings indicator can reach a truly impressive value of sixty percent (compared to devices on the bonded cores). Moreover, the toroidal transformer is much easier to connect with the internal installation of radio electronic devices.

One of the most important characteristics of such electric machines is the shape of the core. It is the ring form that many consider almost ideal. The winding of the toroidal transformer will be much more economical, since due to the uniform symmetrical distribution over the surface of the core, it will be much shorter. In this case, the resistance of the winding will decrease, but the efficiency (efficiency) will increase.

The use of currents of higher densities is also an obvious advantage. This is possible, since the winding is cooled throughout the core. Minimal losses in the iron provide low values of the magnetizing current. This also increases the thermal load characteristics of an electrical device such as a toroidal transformer.

Such machines provide good energy saving indicators. Under load, its indicators reach thirty percent, and eighty - at idle. It is such low scatter rates that are another plus of this type of device. This factor is extremely important when working with electrical circuits of increased sensitivity.
