Abstract

Almost all linear generators used for harvesting wave energy are single-port linear generators (SPLG). The transferred oceanic wave energy to the traditional SPLG is discontinuous in nature due to the variation of waves and its principle of operation. In this chapter, a new design of dual-port linear generator (DPLG) is presented. It can produce enough electrical power from the oceanic wave with adequate amount of voltage while the translator reaches to the top and bottom ends. Stator tooth design greatly affects the efficiency of the DPLG. Genetic algorithm is suitable to determine the optimized stator tooth. The shape optimization method of the stator teeth is presented to justify the performance of DPLG. The force ripples of the DPLG are reduced up to 40.89% by improving its stator tooth shape. It improves the power conversion efficiency of the DPLG as shown in the results and discussion section. The analysis is illustrated with multiphysics simulation and the finite element method to determine the electromagnetic performance. Simulation results along with laboratory prototype are also presented for validation of the DPLG topology. Experimental and simulation results from the prototype show the special interest of applying DPLG as it generates adequate voltage even at zero vertical velocity of the translator obtained from the oceanic wave. It is not possible to achieve by using the conversional SPLG which is mathematically shown. Thus, production of more electrical power from the DPLG is ensured even at the moment of no vertical velocity of its translator.
