TL;DR: In this paper, a bidirectional multilevel dc-dc power converter for energy harvesting from Electro Active Polymer Wave Energy Converters (EAPWECs) is proposed, which is based on a Dual Active Bridge (DAB) converter as main electrical component block.
Abstract: This paper introduces a design, control method and loss model of a bidirectional multilevel dc-dc power converter used for energy harvesting from Electro Active Polymer Wave Energy Converters (EAPWECs), which require high voltage up to 10 kV for operation. To meet all requirements, a modular multilevel dc-dc converter is proposed, which is based on a Dual Active Bridge (DAB) converter as main electrical component block. Two different DAB-based converter designs are presented, which are compared in terms of the total wave power output, thereby reflecting the impact of converter efficiency on EAPWEC-based energy harvesting. Further, the modeled power converter efficiencies are compared to experimentally measured efficiencies in order to prove the accuracy of the loss model.

TL;DR: The magnetic circuit of a linear electric machine is very similar to a rotating electric machine, but they diverge in one fundamental property: the linear generator is open in both ends.

TL;DR: In this paper, the potential of wave power in the Tonekabon area of Iran is assessed based on data from covering the period 2000-2007. But the authors focus on the near-shore wave field and use a wave model to select the optimum locations for a wave farm.
Abstract: Wave energy is produced when electricity generators are placed on the surface of the ocean. The energy provided is most often used in desalination plants, power plants and water pumps. Energy output is determined by wave height, wave speed, wavelength, and water density. In many areas of the world, the wind blows with enough consistency and force to provide continuous waves. There is tremendous energy in the ocean waves. Wave power devices extract energy directly from the surface motion of ocean waves or from pressure fluctuations below the surface. Tonekabon on the north of Iran is subjected to a very wave climate; in this work its potential for energy production is assessed based on data from covering the period 2000–2007. The transformation of the offshore wave field as it propagates into this area is computed by means of a near shore wave model in order to select the optimum locations for a wave farm. Zones emerge as those with the highest potential for wave energy exploitation. Wave power, along with renewable energy-generating sources like tides and streams, is underestimated considering its advantageous physical properties and predictability. This paper examines possible examples of wave power installations in the Tonekabon. The mean power within 50 km of the shore is determined to be (~ 3 kW/m), whereas higher power (~ 9 kW/m) is available further offshore.
