Applications of Step Down Transformers

What is a step down transformer?

A step down transformer is an extremely useful device. It allows us to easily multiply and divide voltage and current in alternating current circuits. Indeed, the transformer has made long-distance electric power transmission a practical reality by allowing AC voltage to be “stepped up” and current to be “stepped down” for reduced wire resistance power losses along power lines connecting generating stations with loads.

Transformers reduce voltage levels at both ends (the generator and the loads) for safer operation and less expensive equipment.

A step up transformer is a transformer that increases the voltage from primary to secondary (more secondary winding turns than primary winding turns).

A step-down transformer, on the other hand, is designed to do the exact opposite.

Types of step down Transformers

1. Single phase Step Down Transformer

2. Center phase Step Down Transformer

3. Multi tapped Step Down Transformers

What are the Applications of Step down transformers?

Step down transformers are broadly used in power adaptors and rectifiers to effectively decrease the voltage. They are also applied in electronic SMPS.

Besides they are also used in the following:

1. National power transmission lines

2. Welding and craftsman machines

3. Voltage inverters and stabilizers

4. Power Generation (220V to 110V conversion and 110V to 220V conversion)

5. Substations

6. Electronic and electrical equipment

7. Doorbells

8. Television sets

9. Refrigerators

10. Musical/entertainment

11. Circuits that use rectifiers

12. Electrical Inverters

13. Medical supplies

14. PCB circuit boards
