This paper presents the design and electromagnetic modeling of a new structure of integrated low-pass LC filter in a buck converter. This micro-filter consists of a planar circular coil placed between two Mn-Zn ferrite substrates. Mn-Zn ferrite has been chosen because of its high permeability and permittivity. In this micro-filter substrates act not only as a magnetic core but also as a capacitor. A modelling of the electromagnetic and electric behavior of the integrated filter, we have simulated with the help of the software PSIM 9.0 on the equivalent electrical circuit of the dimensioned filter. A visualization of the different electromagnetic phenomena that appear during the operation of the filter is determined in 3D space dimension using the finite element method.
