What are flyback transformers?

What is a flyback transformer and what does it do?

A Flyback transformer is one of several transformer design configurations used in switch mode power supply (SMPS) applications. A switching power supply provides two clear advantages over other power supply types: better efficiency due to low power losses, and a compact design. The most common SMPS type is a Flyback converter, which provides the functionality of isolation, energy storage and voltage conversion in one component.

The primary winding of a flyback transformer is connected directly to the input voltage source which stores energy in the transformer. A space (gap) between the core halves helps to store energy during the on cycle of the switch. When the primary winding is “Switched off” from the source, the energy is transferred to the secondary winding, thus powering the load.

At the Premo Group, we develop and design high-quality Flyback transformers (multi-output, coupling, and isolation type ) for Automotive EV/PHV AC/DC onboard battery chargers and DC to DC converters.
