Flyback Transformer: Working Principle, Applications and Selection Guide

Flyback transformer is a crucial component in small power supplies because it enables both voltage conversion and electrical isolation. This is done by means of storage of energy in the core during switching time, followed by the transfer of stored energy to the output. Flyback transformers are usually utilized in AC-DC adapters, chargers, LED power supplies, among others. The choice of the right transformer calls for the consideration of power rating, turns ratio, switching frequency, core…
