DC/DC Flyback

Similar to booster converters in architecture and performance the simple flyback converter topology uses a mutually coupled inductor to store energy when current passes through and releasing the energy when the power is removed. However, the primary winding of the transformer replaces the inductor while the secondary provides the output. In the flyback configuration, the primary and secondary windings are utilized as two separate inductors.
