Abstract

Recently, the interest in offshore wind farms is powerful resource, has been increased significantly because of the stronger and more stable winds at sea, which will lead to a increase power production. DC/DC power conversion solutions are becoming more popular for fulfilling the growing challenges in the offshore wind power industry. This paper presents several multilevel modular DC/DC conversion systems based on the capacitor-clamped module concept for high power offshore wind energy applications. Two types of the capacitor-clamped modules, the double-switch module and switchless module, are discussed. A soft-switching technique is adopted to achieve minimal switching losses and the maximum system efficiency. Theoretical analysis is carried out for the 2n+1 level cascaded configurations based on the capacitor-clamped modules. The inherent interleaving property of the proposed configurations effectively reduces the output voltage ripple without adding extra components. A cascaded hybrid topology is developed by the combination of double-switch and switchless modules. The experimental results of two 5-kW prototype capacitor-clamped converters are presented to validate the theoretical analysis and principles as well as attest the feasibility of the proposed topologies
