Magnetic integration of a planar inductor (20) for a switched power converter including filtering means connected to a load to provide a zero-ripple current. The planar inductor (20) comprises a magnetic core having an E type standardised core section, on the external legs of which are wound, respectively, a first coil (21) and a second coil (22), being magnetically coupled to obtain a leakage inductance (21-2), such that the common magnetic flux observed respectively by both coils (21) and (22) is conducted through the ferromagnetic circuit formed by the external legs of the core, and the magnetic flux associated with the leakage inductance (21-2) is conducted through one external leg and the central leg. <IMAGE> |
