This article explains how to design a SEPIC converter with a coupled inductor. Basic operation Figure 1 shows a simple circuit diagram of a SEPIC con- verter, consisting of an input capacitor, CIN; an output capacitor, COUT; coupled inductors L1a and L1b; an AC coupling capacitor, CP; a ...
Using a coupled inductor takes up less space on the PCB and tends to be lower cost than two separate inductors. The capacitor Cs isolates the input from the output and provides protection against a shorted load. Figure 2 and 3 show the SEPIC 3、 converter current flow and switching ...

The coupled inductor, L1, which is made by Coilcraft®, contains both the primary and secondary inductances needed by a SEPIC power supply. The use of a coupled inductor allows the design to accept half the inductance that a design with two discrete inductors would require.The PCB has been...
Also, the energy stored in the leakage inductance of the coupled inductor is recycled which improves the efficiency more. The steady-state analysis and the design of the converter are discussed thoroughly. Experimental results are provided by a 220W prototype. The results verify the proper ...
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...

The design using a coupled inductor is typical of an automotive input-voltage range with an output power of 64 W. Equation 1 determines that the coupled inductor requires an inductance of 12 µH, with a combined current rating of 13 A (based on IIN + IOUT). This design poses a ...
