A specific prototype and test bench were designed and built to carry out the tests. The results obtained from these tests were used to adjust an in-house mathematical model. The PTO was initially designed to be coupled to a scaled wave energy capture device with a low speed and high torque oscillating motion and high power fluctuations. Any Energy Capture Device (ECD) that fulfils these requirements can be coupled to this PTO, provided that its scale is adequately defined depending on the rated power of the full scale prototype. The initial calibration included estimation of the pressure drops in the different components, the pressurization time of the oil inside the hydraulic cylinders and the volumetric efficiency of the complete circuit. Since the overall efficiency measured during the tests ranged from 0.69 to 0.8 and the dynamic performance of the PTO was satisfactory, the results are really promising and it is believed that this solution might prove effective in real devices.233415908enginfo:eu-repo/semantics/openAccessjournal article10.3390/en5062030power take-offhydraulic PTOwave energy convertersWECvalidation tests of PTOconstruction of PTOmathematical modeling of PTOpower take-offhydraulic PTOwave energy convertersWECvalidation tests of PTOconstruction of PTOmathematical modeling of PTORenewable Energy, Sustainability and the EnvironmentEnergy Engineering and Power TechnologyEnergy (miscellaneous)Control and OptimizationElectrical and Electronic EngineeringSDG 7 - Affordable and Clean EnergyFunding InfoSpanish Government from the PSE-MAR program PS-440000-2008-1Spanish Government from the PSE-MAR program PS-440000-2008-1http://www.scopus.com/inward/record.url?scp=84863606833&partnerID=8YFLogxK
