Abstract

So far, a number of wave energy converters (WEC) have been proposed to increase efficiency and economic feasibility. Particularly, tubular WEC with permanent magnets and coil winding packs is mostly used to convert the wave energy. Due to the demand for high magnetic flux density in WEC, research has been conducted on high-temperature superconductors (HTS) WEC. In this paper, the conceptual design of no-insulation (NI) HTS tubular WEC and its optimization process are proposed. Using NI technology, it has become possible to design WEC with high volumetric efficiency and cost-effectiveness. Furthermore, the design is analyzed in the aspect of electromagnetism, mechanical force, and cryogen. The performance of the proposed WEC is evaluated as a response to various waveforms and their amplitudes. A rectifying circuit of WEC connected in parallel with load resistance is used for the output power study.
