Conversion in Non-Resonant Wave Energy Converter With Floating Buoy

Abstract

This paper studies one of the technical problems that occur in the process of moving from "waves to electricity" in floating wave buoys converters located near the coast: to maximize the product force by displacement. It is proposed a first converter stage only with mechanical elements of low inertia and absence of fluids, showing the advantage of using a accumulator with spring to achieve high accelerations by means of a converter design suitable to mount the mentioned stage. A comparative analysis is made with the most suitable tension for the springs according to the height of the waves provided at the location of the converter.
