Resonant converter building blocks for high power, high voltage applications

This paper presents the use of high frequency resonant power converters as building blocks for medium voltage and high voltage dc architectures. Resonant topologies provide high power density and high efficiency due to their soft switching characteristics. Converter design considerations are investigated along with the interconnection of multiple units in series and/or parallel configurations as well as power flow control requirements. Analysis, simulations and experimental results are presented to prove the proposed methods.
