Primary conversion in non-resonant wave energy converter with floating buoy

Abstract

[Abstract] This paper studies one of the technical problems that occur in the process of moving from ”waves toelectricity” in floating wave buoys converters located near the coast: to maximize the product force bydisplacement. It is proposed a first converter stage only with mechanical elements of low inertia andabsence of fluids, showing the advantage of using a accumulator with spring to achieve high accelera-tions by means of a converter design suitable to mount the mentioned stage. A comparative analysis ismade with the most suitable tension for the springs according to the height of the waves provided at thelocation of the converter.
