Power electronics as grid interface for actively controlled wave energy converters
This factor will be determining for the power take off (PTO) system and will directly affect the dimensioning of the generator and power electronic interface if a direct drive PTO is the chosen solution.
Large-scale ocean wave energy plant modeling
For example the modularity of these systems easily allows a developer to compare how their device performs with a direct drive PTO compared to its performance with a hydraulic PTO.
Development and characterization of a novel direct drive rotary wave energy point absorber MTS-IEEE oceans conference proceedings
A direct drive PTO is best described as a direct connection between the moving bodies of the WEC and the generator.
Performance Evaluation of Wave Energy Converters.
The efficiency is expected to be relatively high and in order to give an order of magnitude, the stated efficiency by the Danish Wave energy program for direct drive PTO systems is 0.85 .
User guide – COE Calculation Tool for Wave Energy Converters : ver. 1.6 - April 2014.
The following table shows the default efficiency values for the hydraulic, water, air, mechanical and direct drive PTO systems (Nielsen, 2003): .
Power conditioning of the output from a linear vernier hybrid permanent magnet generator for use in direct drive wave energy converters
In a direct drive PTO system the wave energy device, such as a heaving buoy or Archimedes wave swing , is directly coupled to the translator of a linear electrical generator, which moves relative to stationary coils mounted on the moored stator.
Comparison of Direct-Drive Power Takeoff Systems for Ocean Wave Energy Applications
This paper begins with a first-order analytical evaluation of 18 direct - drive PTO systems from which five promising devices were identified.
Wave energy converter dimensioning constrained by location, power take-off and control strategy
In this type of WEC we use a Direct - Drive PTO system   to directly convert mechanical into electrical energy.
Estimation of incident wave of AWS-based wave energy converter using extended Kalman filter
Further,due to the direct - drive PTO system,it has a good advantage of the simplified system which reduces the complexity of the system analysis.
