Global Auto Transformer Market - Growth, Trends, and Forecast (Outlook to 2028)

The global autotransformer market is driving due to the growing demand from continuously varying voltage ranges in booster transformers for increasing the voltage in AC feeders and laboratory settings and as a voltage stabilizer. The rising need for electrification and the increasing demand from electrical grids and systems in rural areas, especially in developing and underdeveloped economies. The government initiatives support large scale integration of the products in the global autotransformer market and shift focus towards renewable or sustainable energy sources.

The copper winding costs reduced by installing autotransformers are also the major factor driving investment in this market. The autotransformers employ only a single winding of copper wiring per phase compared to two separate windings utilized in conventional voltage transformers.

In audio applications, autotransformers adapt speakers to constant voltage audio distribution types by matching the impedance. In railway applications, autotransformers link contact wires to the rail supply conductors, increase usable transmission distance by increasing voltage, and reduce interference with external equipment.

A single winding transformer that is both conductive and inductive is known as an ‘autotransformer.’ An autotransformer that has a common winding in both the primary and secondary circuits. Unlike two-winding transformers, power is transferred both inductively and conductively in autotransformers. The autotransformers are used as starters for induction motors and synchronous motors, known as autotransformer starters, in labs for obtaining a varying voltage, in voltage stabilizers as regulating transformers, and as booster transformers to raise the voltage in AC feeders the autotransformer is used.

Variable Auto Transformers can adjust the voltage to the load smoothly from zero to the rated supply voltage. If the supply voltage was tapped at some point along the primary winding, the output secondary voltage could potentially be higher than the actual supply voltage.

Autotransformers are employed for small voltage changes. In substations, where large voltage variations are unnecessary, the autotransformers can replace large, expensive power transformers. Additionally, autotransformers have better voltage regulation than conventional transformers, and utilities install autotransformers to provide different voltage points along its winding. However, due to the lack of primary to secondary winding isolation, these transformers are not appropriate for stepping down higher voltages.

Autotransformers are typically used to convert local distribution supply voltage to some other secondary voltage on the secondary side required for specific electrical devices. This conversion is often from 125 Volts to 250 Volts or 250 Volts to 125 Volts. Unlike isolation transformers, variable autotransformers use a single winding and offer no interference or disturbance. In addition, the autotransformer supports a load equal to its rated value whether connected in the 125 Volts to 250 Volts configuration or the 250 Volts to 125 Volts configuration.

By type, Global Autotransformer Market has been segmented into Step down transformer and step up transformer. Step up transformer is a type of transformer that converts the low voltage and high current into high voltage and low current. Step down transformer acts reverses to the step down transformer converting high voltage and low current into low voltage and high current. Based on the application, the transformer type to be used is decided.

Autotransformer market opportunities:

• An increase in manufacturing activity and electrification initiatives in Asian countries like India, Bangladesh, Vietnam is a significant driver for the autotransformer market.
• Automation and modernization of electrical infrastructure in the North American (United States, Canada, Mexico) and European regions (United Kingdom) will stimulate demand for autotransformers.

Autotransformer market restraints:

• The usage of autotransformers is limited to places where a slight variation of the output voltage from input voltage is required.
• Lack of commercialization of autotransformers wrt to the transformers.

The power utility segment accounted for a major autotransformers market share. Power utilities take care of maintenance, operation, voltage regulation, and grid infrastructure, coupled with the realization of consumed electricity and energy efficiency projects. 

The Global  Autotransformer Market comprises sales of autotransformers for power transmission and distribution, residential and commercial projects, and industrial applications.
