    Abstract

    This paper presents the analysis and design of a new class of multiphase converter for high-to-low voltage applications. The converter features a V i / n voltage stress on the primary-side switches, which are commutated under zero voltage switching (ZVS), and Io / n current stress on the output inductors and rectifier diodes. A DC analysis allows for deriving the duty-cycle loss and the ZVS load range. A trade-off design is performed for optimizing these two conditions. The proposed converter is favorably compared with available solutions from the point of view of number of switches and the voltage stress to which they are submitted. Experimental results based on a 1500V/48V, 2 kW prototype verify the theoretical predictions.
