A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction. There is an electromagnetic induction that produces an electromotive force within a conductor, which is exposed to time varying magnetic fields. Transformers are used to increase or decrease the alternating voltages in electrical power applications.

Buck Boost Transformer
Buck boost transformers are a type of transformer that are used to make adjustments to the voltage that is applied to alternating current equipment. The Buck boost connections are used in several places such as uninterruptible power supply (UPS) units for computers.

Control Power Transformer
A control transformer is an isolation transformer that provides good voltage regulation, and it is also designed to provide a high degree of secondary voltage stability (regulation) during a brief period of overload condition (also referred to as “inrush current”).

Distribution Power Transformers
Distribution transformers are used for lower voltage distribution networks as a means to end user connectivity. The varieties include 11kV, 6.6kV, 3.3kV, 440V, and 230V). They are generally rated less than 200 MVA.

Encapsulated Transformer
Encapsulated transformers are transformers in which one or more of the transformer’s components are completely sealed. The one example of a component is the transformer’s coils. The process of encapsulation protects the transformer from dirt, dust, moisture and any other contaminants.

Isolation Transformer
An isolation transformer is a transformer that is used to transfer electrical power from a source of alternating current (AC) power to some equipment or device while isolating the powered device from the power source, usually for different safety reasons.

Power Supply Transformers
A power supply transformer is an iron-core transformer that has a primary winding that is connected to an alternating-current power line and one or more secondary windings that provide different alternating voltage values. In an alternating current electrical system, a device for transforming the source of electrical supply from one voltage to another.
