On this slide, you can see a typical layout of a SEPIC converter from Linear Technology which uses two 22µH inductors, or L1 and L2, in the circuit. The capacitor, C6, basically splits the windings in a primary and a secondary. This design can now be done like shown in this example by using 2 individual inductors with 22µH, but there are clear advantages when using one of Wurth Electronics coupled inductors in this design. The construction and the advantages of a coupled inductor will be shown on the next slides. 4
A coupled inductor basically consists of two identiical windings wound onto one core. The important criteria is that the windings are exactly identical to generate the coupling effect in a SEPIC converter. 5
