Description: In aeronautics field, the constraints are such as the mass of the filters can represent up
to 50 of the total mass of the converter. During the last years, magnetic coupled interleaved
converters enhances performances (power density, efficiency, transient response). It existe
several possibilities for use interleaved coupled topologies that use inter-phase transformer
exist, the main objective of this study is to find among these topologies the best adapted
configuration in the context of a three-phase voltage inverter 110Veff/400Hz 25kVA. The
choice of the magnetic material type has a great impact on determining the weight, the
volume and the losses of the converter. Parallelization leads to increase the semiconductor
number. These new structures must guarantee at the same time a raised efficiency, a low mass
and a great reliability, even in the event of case of breakdown of a power semiconductor-In aeronautics field, the constraints are such as the mass of the filters can represent up
