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
