When the input voltage is delivered to the primary winding during each cycle, energy is stored in the gap of the core.
What is a Flyback Transformer?Ī flyback transformer is a gapped-core coupled inductor. Because they have a gapped core and store energy in the core, flyback transformers are also classified as coupled inductors. Flybacks are distinct from other topologies, such as forward-mode, in which energy passes from primary to secondary quickly. The gapped-core structure of flyback transformers allows for significant energy storage without saturating the core.
Of course, you can use our online flyback transformer calculator to do the flyback voltage calculation.įlyback Converter Operation and Voltage Equation Flyback Controller Overviewĭuring the first half of the switching cycle, energy is stored in the magnetic field of the transformer, and then released to the secondary winding(s) linked to the load during the second half of the cycle. You can follow its instruction to calculate the flyback voltage.
This following Youtube video explains the current flow and operation of the flyback converter with the active switch on and off in continuous conduction mode (CCM) and average steady state. In fact, this flyback converter tool is a online flyback transformer calculation tool. The dots in the flyback converter are inverted, whereas the dots in the forward converter are aligned.įor the different windings of a discontinuous mode flyback converter, the flyback transformer design tool above will help you to calculate the number of wire gauge, inductance and turns. By comparing the orientation of the dots on the secondary to the primary, you can discern the difference between the two topology. When the switching transistor is switched on, energy is transmitted to the secondary windings, as opposed to a forward converter topology, in which energy is sent to the secondary windings when the switching transistor is turned on. The field collapses when the transistor is switched off, and the energy is transmitted to the secondary windings. However no energy is delivered to the secondary windings. The main winding of the flyback transformer is electrified when the switching transistor in a flyback converter is turned on. Introduction of Flyback Transformer Design Tool
