Abstract (en)

[origin: WO2020055320A1] A power take-off device (100) for use in a wave energy converter having a prime mover (404), the power take-off device having a PTO frame (110). A direct drive motor (14) mounted to the PTO frame (110) and electrically connected to an energy storage (16), a means (12) for converting linear motion from the movements of the prime mover (404) to rotary motion to the direct drive motor (14), and control means (206) adapted to control the direct drive motor (14) to apply a torque to the means for converting linear motion of the prime mover (404) into rotary motion to control the power take-off force by means of storing and retrieving energy in the energy storage (16) while outputting constant power to an output cable of the power take-off device. A wave energy converter and a wave energy converter system are also provided.
