Design of a hydraulic power take-off test rig for wave energy converters

a hydraulic test bench for a wave energy converter was designed and built. Reciprocating motion generated by incident wave was rectified by a hydraulic circuit, and the rectified flow drives a generator. In this experiment, total efficiency was 40% to 50% using 48-pole generator. Also a Simulink program was made to simulate the hydraulic circuit. Power of the reciprocating motion by the incident wave was rectified by 4-way valve.
