Coupled Inductor for DC-DC Converter ~50W
A coupled inductor is also known as a flyback transformer. It is intended to operate in a different mode from what is traditionally called a power transformer. You are correct that a traditional power transformer does not store appreciable energy. A fly-back transformer, on the other hand, stores energy for part of its &quot;cycle&quot;, and then releases that energy, through the &quot;secondary&quot;, during another part. It is essentially an inductor with two magnetically coupled coils.
