摘要： Disclosed are a wave force generation system for producing electric energy by a hydraulic circuit and a controlling method. The wave force generation system comprises a power conversion portion including a hydraulic cylinder which generates a hydraulic pressure by six degrees-of-freedom motion of a moving object floating on waves, wherein: when force is applied to the hydraulic cylinder in one direction thereof, the power conversion portion makes a fluid flow along a first path so as to produce electric energy; and when force is applied to the hydraulic cylinder in the other direction thereof, the power conversion portion makes the fluid flow through second path which makes the fluid bypass and flow in a direction opposite to the first path, whereby the fluid in the second path meets the first path and thus can produce electric energy.
