Conception et réalisation d’un Flyback à huit cellules 28V-300V-12kW utilisant des transformateurs intercellulaires

A low-input voltage - high power realization is presented with the aim to demonstrate the feasibility and the interest of topologies using InterCell Transformer. They constitute a promising option to interleave converter stages and so, can answer to the specifications considered in this paper. In a first part, the operating principle of the ICT flyback converter is recalled. The second part presents briefly the main features of the design. The last part presents the design and the implementation of the complete flyback converter using 8 cells. In the end, the experimental results are presented and discussed.
