Toroidal Power Transformers Market Research Findings, Market Growth Factors Analysis and Forecasts to 2025


Toroidal Power Transformers Market is segmented into application, product and geographical regions. A toroidal transformer has ring type core made from cold rolled grain oriented (CRGO) Silicon steel strip devoid of any joints and annealed for stress relief after being wound. These wound cores are then suitably insulated by class B insulation and the winding of copper wire is usually done by winding machines. In Toroidal Power Transformers the core is permanent, devoid of any air gap and the path of flux being along the direction of grain orientation, gives an occasion for optimum use of flux density, in addition very low iron loss and exciting current. The primary and secondary windings are closely linked magnetically. Therefore, the leakage fluxes and reactance are negligible.
A toroidal transformer has its winding spread over the entire periphery of the core. This results in larger area for dissipating the heat. Till date, all such small low voltage type transformers needs were met approximately universally by traditional or conventional El transformers.Now materials are easily available, so it has been possible to develop low voltage transformers giving a whole set of advantages and wide range of applications in place of conventional transformers.

Doughnut shaped toroidal transformers save space compared to E-I cores, and sometimes to reduce external magnetic field. These use a ring-shaped core, copper windings wrapped round this ring (and thus threaded through the ring during winding), and tape for insulation. Toroidal transformers have a lower external magnetic field as compared to rectangular transformers, and can be smaller for a given power rating. Though they cost more to make, as winding requires more complex and slower equipment. They can be mounted by a bolt through the center, using washers and rubber pads or by potting in resin.

The toroidal transformer construction, although generally more expensive than E-I laminated core types, provides a smaller and lighter transformer than for a given power rating together with higher efficiency and less leakage of magnetic field around the transformer.

Toroidal Power Transformer Market is segmented by Application into Medical equipment, Audio/Video products, Motor control equipment, Lighting, stabilized power supplies, Microprocessor based units, Battery chargers, Telecommunication products,
