Wave-Activated-Body Energy Converters Technologies: A Review

Abstract

Ocean wave provides promising energy resource in supplying the electricity for many parts of the world especially to the countries that surrounded by ocean water. In view of the fact that the ocean wave could convert the energy more than half from its potential capacity of the time, compared with wind or solar system which is less than half of its capacity resource. However, the challenge rises on designing the ocean waves capturing device that can achieve optimum efficiency. This paper addressed several topics including the overview of existing technology of wave energy converter with emphasised on wave-activated-body category; current principle of energy harnessing; types of generators that utilized to harness the wave energy; and the current technologies of power electronics that implemented to ocean wave devices.
