Which transformer is used in electronics?

In electronics, various types of transformers are used depending on the application. Here are some common types:

1. Step-Down Transformers: Used to reduce voltage levels for devices that require lower operating voltages than the supply voltage.

2. Isolation Transformers: Provide electrical isolation between circuits, often used to protect sensitive electronics and improve safety by preventing direct connection between high-voltage and low-voltage circuits.

3. Autotransformers: Used for voltage regulation and can step up or step down voltage with a single winding that acts as both the primary and secondary.

4. Pulse Transformers: Used in digital circuits and switching power supplies to transmit pulses without distortion and with precise timing.

5. Flyback Transformers: Common in switched-mode power supplies and CRT displays, they store energy and release it in pulses to provide the necessary high voltage.

6. Toroidal Transformers: Used in various electronic devices for efficient power transfer with low electromagnetic interference, often found in audio equipment and medical devices.

Each type of transformer is selected based on its ability to meet the specific voltage, current, isolation, and frequency requirements of the electronic device or circui
