Comparison of Two Alternative Hydraulic PTO Concepts for Wave Energy Conversion

, 2011
Hydraulic Power Take Off (PTO) systems for wave energy usually fall into two broad categories. These are, firstly, variable pressure systems where control of the primary force/torque is achieved by pressure modulation, and secondly, constant pressure systems where control of the primary force/torque is achieved by valve transitions that select between ...

An Integrated Tuned Hydro-PTO Semi-Submersible Platform for Deep-Sea Wind-Wave Cogeneration: Design, Hydrodynamic Analysis

Energies
The ocean offers abundant wind and wave energy resources. This paper proposes an integrated concept that co-locates a semi-submersible floating wind platform with wave energy converters (WECs) to exploit the geographical consistency of these resources ...

High-frequency current source converter for a direct drive powertrain in a wave energy converter

The Journal of Engineering, 2019
Wave energy converters (WECs) generally use a mechanical solution such as hydraulics or gearing to optimise the extraction of energy from the incoming waves prior to converting it into electrical energy via a high-speed rotating generator.
