An auxiliary resonant-commutated pole (ARCP) ensures soft switching in the entire operation range of a three-phase dual-active bridge dc-dc converter. This work evaluates the design and the resulting boost in system efficiency for different semiconductor materials and devices. Afterwards, a full-scale medium-voltage prototype of an ARCP is constructed. The subsequent measurements are presented within...
The paper presents a design of a 2kW Resonant Power Supply dedicated for telecom applications. The power supply is based on a series-parallel LCLC resonant converter, which has some interesting features, such as self protection from load short-circuit. The design comprises an integrated magnetic component intended to be used as the resonant tank inductors. The construction presented in the paper allows...
This paper presents methodologies for the structured modeling and analysis of dual-output dc–dc resonant power converters. The work is underpinned by a generalization of classical fundamental mode analysis (the most prevalent technique for the analysis of single-output converters) with a progression of increasingly accurate linear load-modeling extensions (at the expense of computational complexity)...
The paper is concerned with new resonant converter configurations, belonging to the previously published dual channel dc-dc converter family. On one hand, the new configurations solve a significant shortcoming of the original ones, namely, the output midpoint potential was floating in comparison with the input midpoint. This caused a high-frequency oscillation of the output midpoint, often significantly...
