摘要： A wave energy converter (10) comprises an energy absorption unit (100) arranged to absorb energy generated by movements of water when the wave energy converter is arranged in a pool of water, an energy accumulation unit (200) connected to the energy absorption unit, and a power generation unit (300) connected to the energy absorption unit. The energy accumulation unit is arranged to accumulate energy from the energy absorption unit when the energy absorption unit absorbs more power than the power generation unit generates and to dissipate energy to the power generation unit when the energy absorption unit absorbs less power than the power generation unit generates. By providing hydraulic components in these units, an efficient and flexible wave energy converter is provided.

摘要： A power take-off device for use in a wave energy converter comprises a buoy (1) and a means (2, 3) for converting linear motion from movements of the buoy (1) into rotary motion comprising an elongated means (2) and rotary devices (3) interacting with the elongated means, wherein whereby the rotary devices (3) in the power take-off device preferably are flexibly suspended by wire (33) in support structure (30a) fixed with the buoy (1). By providing means (7a) for applying an essentially constant pre-tension force on the buoy (1), connected to a rotary device (3), and means (7b) for applying a variable damping force on the buoy (1), connected to a rotary device (3), wherein the variable damping force is superimposed on the pre-tension force, whereby, during operation, a unidirectional torque is applied on the rotary devices (3) by the combination of the means (7a) and the means (7b), to combine control of the resonance frequency of the buoy as well as control of the damping to extract power, with the purpose to increase the power capture and reduce design complexity.

摘要： A wave energy converter (1) includes a buoy (3) and a transmission unit (2). In the transmission unit there is a driveshaft (11), which is driven to rotate either when the buoy rises or sinks, yet always in the same direction. The driveshaft is mechanically coupled to one of the rotating parts (21') of an electric generator (21) and drives this to generate electric current. Further on there is an energy accumulation device (105), which is also coupled to the driveshaft to accumulate energy when the buoy rises or sinks and the driveshaft rotates and which is then used to drive the generator at the other of the rising- and sinking motions. The coupling between the energy accumulation device and the driveshaft can go by the generator's second rotatable part (21'), the air gap between the generator's parts and the generator's first part. The coupling over the air gap gives a torque, which drives the second part to rotate along and which also counteracts the rotation of the driveshaft. The generator's second part is driven by the energy accumulation device to rotate in the other direction, when the torque from the driveshaft does not exceed the counteracting torque.

摘要： A wave energy converter (10) comprises an energy absorption unit (100) arranged to absorb energy generated by movements of water,a power smoothing unit (200), a power generation unit (300) and an energy storage device (5; 5b), these units being adapted to cooperate to achieve a smooth power output from the power generation unit. The power smoothing unit is arranged to accumulate energy from the energy absorption unit in the energy storage device when the energy absorption unit absorbs more power than the power generation unit generates and to release energy from the energy storage device to the power generation unit when the energy absorption unit absorbs less energy than the power generation unit generates. A first transmission device (2) is provided between the energy absorption unit (100) and the power smoothing unit(200)or the power generation unit (300), and adapted to transfer energy absorbed by the energy absorption unit to the power smoothing unit and/or the power generation unit. A second transmission device (4) is provided between the power smoothing unit (100) and the energy storage device (5; 5b), and adapted to transfer energy between the units, wherein the power smoothing unit (200) and the power generation unit (300) are located separately from the energy absorption unit (100).
