What makes a toroidal transformer so distinct and unique is its characteristic construction and design. It possesses a toroid or ring-shaped magnetic core, made of iron powder or ferromagnetic material, around which the wires are wound, which work on the principle of electromagnetic induction. The current flows through the primary winding, which induces an electromotive force, followed by the flow of current in the secondary winding. Operating with a fully-loaded capacity, functioning continuously or intermittently, these transformers are available in various capacities.
Where and why are toroidal transformers used?
Toroidal transformers find use in electrical systems across industries, ranging in power distribution, LED lighting, telecommunication, industrial control systems, biomedical instrumentation, aerospace, audio/video devices, and amplifiers. In recent years, the demand for toroidal transformers has increased due to the distinct benefits that they offer, some of which being as follows.
- Toroidal transformers have a unique and compact design, which makes them suitable for usage in even cramped up spaces.
- The design and construction of the toroidal transformer makes it very light in weight, thus easy to handle.
- The design and winding pattern of the wires reduce the number of coils, which in turn helps decrease the electromagnetic interference and resistive losses.
- Toroidal transformers are also resistant to external EMI as the windings on the toroidal core are absolutely compact, without any gaps in between.
- The design improves the electrical performance and overall efficiency of the transformer, with the short windings acting as a shield, helping the system stay at a lower temperature.
- The short length of the windings also reduces the humming sound, making it an almost noiseless transformer.
- The short length of the windings creates a close to ideal magnetic field.
- The energy required to maintain the magnetic field is much lesser in toroidal transformers as compared to other kinds of transformers.
- The toroidal shaped cores facilitate almost 100% utilization with minimal energy dissipation.
- Toroidal transformers can be easily customized, which means that they do not have compatibility issues with most equipment.
- Toroidal transformers are relatively very cost-effective.
