Modelling and Analysis of Five-phase Coupled Buck Converter Using Intercell Transformers
Résumé
Interleaved power converters are now used in many different conversion systems. With the development of power integration technologies, interleaved parallel converters using Intercell Transformers with a possibly high number of cells are evaluated. In the first part of this paper, an analytical model of multiphase coupled Buck converter is proposed. This model is useful to show the limits associated with the conventional supply of such converter (supply voltages forming a direct poly-phase system). In the second part of the paper, an optimized voltage supply improving the performances of the system is introduced. Experimental results validate the approach.
