Types of Transformers and Their Applications

Click on the flashcard to see the answer

What is a step-up transformer?

A step-up transformer increases the voltage from primary to secondary winding.

What is a step-down transformer?

A step-down transformer reduces the voltage from primary to secondary winding.

Name an application of isolation transformers.

Isolation transformers are used for decoupling two circuits, ensuring that they have no direct electrical connection.

What is the role of an autotransformer?

An autotransformer uses a single winding to act as both the primary and secondary winding for voltage step-up or step-down.

What is the key advantage of toroidal transformers?

Toroidal transformers have a lower electromagnetic field due to their donut shape, causing less interference.
