A power take-off of a wave energy converter is a mechanism with which the absorbed energy in the form of mechanical/pneumatic/potential energy from the primary energy conversion stage is transformed into useful mechanical energy for further energy conversion, mostly into electricity if a generator is connected to the PTO.

Scientific Fundamentals

Power Conversion Principle

For power conversion, it can be made using either translational or rotational motions and their corresponding PTO force or torque. When a translational motion is used for power conversion, the capture power by the PTO is calculated as
$$ P={F}_{pto}\cdot V $$
