What is the difference between a flyback transformer and a normal transformer?

A flyback transformer and a normal transformer serve different purposes and operate under different principles.

1. Operational Principle:
2. Normal Transformer: A normal transformer operates on the principle of electromagnetic induction, where alternating current (AC) in the primary winding induces a changing magnetic field in the core, which then induces a voltage in the secondary winding.
3. Flyback Transformer: A flyback transformer is a type of transformer used in electronic circuits to generate high voltage pulses. It operates by storing energy in its magnetic core during the "on" time of the primary winding and then releasing it during the "off" time, producing a high-voltage pulse in the secondary winding.
4. 2.Application:
5. Normal Transformer: Normal transformers are commonly used for voltage transformation in power distribution systems, such as stepping up or stepping down voltages in electrical grids.
6. Flyback Transformer: Flyback transformers are typically used in applications where high voltage pulses are needed, such as in CRT (cathode ray tube) displays, switching power supplies, and certain types of inverters.
7. 3. Configuration:
8. Normal Transformer: Normal transformers usually have two or more windings wound around a common magnetic core. They are designed to transfer energy efficiently between different voltage levels.
9. Flyback Transformer: Flyback transformers are often designed with a primary winding and a secondary winding, but they may also include additional windings for feedback or auxiliary functions. They are configured to store and release energy in a controlled manner to produce high-voltage pulses.
10. 4. Operation Mode:
11. Normal Transformer: Normal transformers operate continuously as long as AC power is supplied to the primary winding.
12. Flyback Transformer: Flyback transformers operate in discontinuous mode, with energy stored during the "on" time of the primary winding and released during the "off" time.

In summary, while both transformers involve the transfer of energy through electromagnetic induction, they have different designs, applications, and operational principles. Normal transformers are used for continuous voltage transformation, while flyback transformers are employed for generating high-voltage pulses in a controlled manner.
