Abstract: The present invention provides an oscillating water column-oscillating buoy combined wave energy converter. The present invention combines the advantages of the wave energy converters of the oscillating water column and the oscillating buoy. The conversion principles of wave energy of the oscillating water column and the oscillating buoy are on the contrary. The oscillating water column works when the structure does not move, while the oscillating buoy works when the structure substantially vibrates. The oscillating water column and the oscillating buoy are respectively operated in respective spectral ranges without affecting each other, thereby expanding the effective frequency band width of wave energy conversion. Due to the characteristic of absorbing the wave energy at all directions of 360°, the absorption efficiency of the wave energy is enhanced. Through the adoption of a fixed structure, stability of the converter can be ensured, generating efficiency is enhanced and maintenance is facilitated.
