Electrical transformers are used in everything from toys, electronic charging devices, and small appliances to lighting systems and medical equipment. But you’re here for answers to your important electrical transformer questions, so let’s get straight to the point.
What Is an Electrical Transformer?
Electrical transformers are devices that transfer electric energy from one AC circuit to another circuit by stepping up or stepping down voltage without changing frequency.
The three main components of an electrical transformer are:
- Laminated magnetic core
- Primary winding (also called primary coil)
- Secondary winding (also called secondary coil)
Both the primary and secondary windings are connected to the laminated magnetic core. The mutual induction between these circuits helps the transfer of electricity.
What Does an Electrical Transformer Do?
- Increase or decrease line voltages for integrated circuit or other specialized circuit operations
- Aid with the transformation from AC voltage to DC voltage
- Distribute and regulate power
- Improve the safety and efficiency of power systems
How Does an Electrical Transformer Work?
This is how an electrical transformer works:
- An electrical current enters the transformer via a connection to the primary winding coil.
- The primary winding converts the electrical power into a magnetic field.
- The magnetic field flows through the laminated magnetic core.
- The magnetic field flows into the secondary winding coil.
- The secondary winding coil turns the electromagnetic flow back into electrical power at the necessary output voltage.
What Are the Types of Electrical Transformers?
- Communication transformers are used in the telecommunication industry, generally on physical circuits.
- Digital audio transformers maintain highly accurate and minimally distorted signals for very high frequencies when wanting to improve sound quality.
- Flyback transformers (also called line output transformers) are used for power and electrical supply conversion and AC-DC power supplies.
- Gate-drive transformers are used for triggering IGBTs in applications like motor drives, unregulated and switch mode power supplies, and inverters.
- Isolation transformers are often used in the medical industry to reduce the risk of shock to a patient.
- Power transformers have many uses, including motor drives, unregulated power supplies, traction motor control, and induction heating.
