The North America toroidal power transformers market size is projected to reach USD 1.50 billion by the end of 2025. Increasing application of toroidal transformers in the field of medical, power distribution, smart grid, and other power electronics is one of the key factors driving the market. In addition, reduction in weight and size and improved efficiency of current toroidal transformers as compared to traditional EI core transformer are also adding to the growth. The region has presence of multiple toroidal power transformer manufacturers.

Stringent government regulations in North America regarding the usage of high-quality toroidal transformer are projected to increase competitiveness, which will add to the growth of the market for toroidal transformers. U.S. accounts for around 70% value share and is home to many toroidal transformer manufacturers. The manufacturing process for toroidal transformers majorly includes winding machines where secondary winding is done on ferrite core.

Furthermore, a layer of insulation is covered over the windings. Later, secondary windings are done over the insulator and outer insulation is done to cover the final body of the transformer. Winding accounts for approximately 45% of the total manufacturing processes as various types of winding machines are involved during the assembly of the transformer. Insulation accounts for minimal share owing to the low price of components, such as cables or connecting wires.

Renewable share of North America’s electricity mix is expected to rise from 2015 to 2025. However, usage of conventional power transformers increases environmental pollution. Therefore, there is an increasing need to lower carbon emissions and conserve water in existing and new power plants. Use of renewable energy sources can lower the negative impact on the environment. Technological advancements have made it easy for utilizing renewable sources for power generation.

In terms of types, isolation toroidal transformer held the major market revenue share in 2017 owing to better efficiency, increased power output, less magnetic stray fields, and excellent acoustic properties. Isolation transformer is the preferred choice for many medical equipment for research labs and hospitals in North America.

Autotransformers are significantly cheaper than isolation transformers owing to the presence of single winding, which makes them smaller, lighter, and efficient in many step-down applications. Autotransformers are typically used in bulky three-phase electronic power distribution.

Toroidal core transformers are small in size. This has increased their usage in computer, audio systems, TV, and other such appliances. This is further adding to their demand. On the basis of application, distribution segment led the market in 2017. Medical equipment held a market revenue share of nearly 30% in 2017 and is estimated to be the fastest-growing application segment. It is projected to witness a CAGR of nearly 8% over the forecast period.

North America’s toroidal power transformer market is highly fragmented in nature and is marked by technological advancements. Some of the key companies in the North America toroidal power transformers market include Powertronix; Precision, Inc.; Meramec; Bicron; Talema; Plitron; Pacific Transformers; Miracle; Toroid Technology; Eaton; Wurth Elektronik; Analog Devices; Amgis; Triad Magnetics; Hammond Manufacturing; Abracon; Toroid; Schneider Electric.
