Hydrostatic transmission development for wave energy converters

The aim of this paper is to develop an innovative approach for electric power conversion from the vast ocean wave energy. Here, a floating-buoy wave energy converter (WEC) using hydrostatic transmission (HST), which is shortened as HSTWEC, is proposed and designed to enhance the wave energy generation task during wave fluctuations. In this HSTWEC structure, the power take-off system (PTO) is a combination of the designed HST circuit and an electric generator to convert mechanical energy generated by ocean wave into electrical energy. Several design concepts of the HSTWEC have been considered in this study for an adequate investigation. Modeling and simulations using a co-simulation between MATLAB/Simulink and AMESim have been carried out to evaluate these design concepts to find out the best solution for designing the WEC device.
