Design of a 28 V-to-300 V/12 kW Multicell Interleaved Flyback Converter Using Intercell Transformers

摘要: A low-input voltage high-power realization is presented with the aim to demonstrate feasibility and interest of topologies using intercell transformer. They constitute a promising option interleave converter stages, therefore, can answer specifications considered in this paper. These require galvanic insulation chosen topology Intercell Transformer (ICT) flyback converter, previously proposed by authors. In first part, operating principle ICT recalled. The second part presents briefly main features transformer design, more precisely described previous This includes discussion about choice cell number. last design implementation complete eight cells. preliminary work concerns choice, test each elements, mainly primary switching stage. end, experimental results are discussed. potential original that needs only one level magnetic components. Considering suitability interleaving for high-power-low-voltage applications, constitutes good candidate field.
