6 FAQs about [Flyback transformer energy storage principle]
How does a flyback transformer work?
During each cycle, when the input voltage is applied to the primary winding, energy is stored in the gap of the core. It is then transferred to the secondary winding to provide energy to the load. Flyback transformers are used to provide voltage transformation and circuit isolation in flyback converters.
What happens if a flyback transformer needs more energy?
If the load requires more energy at this point, the energy storage capability of the transformer will be exceeded and the load will not receive the required energy. This will lead to loss of regulation, therefore the peak primary current (Ipk) or primary saturation current (Isat) of a flyback transformer is a critical parameter.
