Toroidal Power Transformers Market: Overview

Transformers with toroidal (doughnut or ring) magnetic cores are known as toroidal transformers. A wire is twisted around a doughnut-shaped or circular ring core made of ferromagnetic materials like iron powder, ferrite, or laminated iron. These cores are electrically passive parts. Compared to conventional shell & core-type transformers, toroidal transformers offer greater efficiency, design flexibility, and compact design. Due to their superior electrical performance and symmetry, toroidal-shaped cores are used much more frequently. Additionally, this restricts the ability of magnetic flux to leave the core.

The operation of a toroidal transformer is similar to that of an iron core transformer. The toroidal transformers are put together over a ring-shaped core manufactured from a long strip of silicon steel, permalloy, or ferrite twisted into a coil, depending on the frequency. The strip construction ensures that all grain boundaries are pointed in the best direction. This aids in lowering core reluctance, increasing the transformer’s effectiveness.

The ring form of the core eliminates the built-in air gaps that are present in the manufacturing of EI-shaped cores. The primary and secondary coils are concentrically twisted to cover the whole surface of the core. This reduces the length of wire required and also provides screening to stop electromagnetic interference from being produced by the magnetic field of the core. At frequencies up to a few tens of kilohertz, ferrite cores are employed to cut losses, especially in switch-mode power supply.

Growth Factors

The main driver boosting demand for toroidal power transformers is the growing use of toroidal transformers in power electronics, smart grids, medical, and other power distribution applications. Over the projected period, it is also anticipated that existing toroidal transformers’ decreased weight, size, and greater efficiency in comparison to conventional EI core transformers will further fuel demand.

Government restrictions regarding toroidal transformer quality are expected to increase competition among producers. In the approaching years, it is expected that this aspect would further boost the regional toroidal power transformer market.

Segmental Overview

The market for Toroidal Power Transformers is segmented into product type, rating, and application. Based on product type, isolation transformers held the greatest market share in 2021. Over the forecast period, it is expected that decreased magnetic stray fields and improved efficiency, power output, and acoustic qualities will propel growth. Many hospitals, research labs, and medical equipment manufacturers prefer to use isolation transformers.

Because autotransformers have a single winding, which makes them more compact, lighter, and effective in many step-down applications, they are much less expensive than isolation transformers. When distributing hefty three-phase electronic power, autotransformers are frequently employed.

Transformers with toroidal cores are compact. Their usage in computers, audio systems, TVs, and other consumer electronics has expanded, fueling their growth even further. The fastest-growing application in terms of revenue in 2021 was medical equipment, which had a market share of close to 30%. The CAGR of market is anticipated to grow at a significant.

Regional Overview

During the forecast period, Asia Pacific is anticipated to dominate the global market. It is anticipated that the markets in North America and Europe will expand on average during the projected period. During the forecast period, a small portion of the worldwide toroidal transformer market is expected to come from Latin America, the Middle East & Africa.
