The traditional wave energy converters (WECs) use hydraulic or turbine-type power take-off (PTO) mechanisms which consist of many moving parts, creating mechanical complexity and increasing the installation and maintenance costs. Linear generator-based direct-drive WECs could be a solution to overcome this problem, but the efficiency of the single conventional linear generator is not high enough, and it cannot work satisfactorily in the low-frequency range. This article reviews the recent research developments of the linear permanent magnet (PM) generator-based WEC to harness maximum energy from ocean waves. It starts with a brief introduction and background of wave energy converters using linear generators. Following this, the working principle of the WECs with linear PM generators is briefly outlined. Subsequently, the analytical model of the linear PM generator-based WEC is studied. After that, the up-to-date developments of the linear PM generator-based PTO systems are studied. Despite some modifications resulting in complexity in the linear PM generator’s structure and a rise in manufacturing costs, the study shows the systems’ efficiencies increased by increasing magnetic flux and reducing cogging force. The key parameters and improvement issues that can increase the performances and efficiencies of the PTO systems are identified to help future researchers for further development. Moreover, the review discusses the numerical and experimental analysis tools, the typical control systems used by the researchers and the challenges of the linear generator-based wave energy conversion system. Finally, conclusions about the significant beneficial characteristics and design choice of the WEC linear generator structure are provided and related to the application conditions.

Permanent magnet linear generator (PMLG) is mostly applied to oceanic wave energy conversion systems because of its excellent conveniences. But the conventional PMLGs suffer from much core loss and demagnetization because of armature reaction during operation, which are responsible for the electrical power generation. To overcome this problem, standard and advanced magnetic materials are applied to the PMLG for analysis in this paper. At first, a PMLG is designed to test the effect of using the advanced magnetic materials. Further, the PMLG is analyzed with standard steel core and M4-Carlite magnetic core along with two neodymium iron boron permanent magnets namely N30H and N48H. Construction, working principle, and mathematical model of the PMLG are presented. Demagnetization curves of N30H and N48H permanent magnets, magnetization, and core loss curves of the standard steel core and M4-Carlite magnetic core are presented for comparison. Simulation works are executed by finite element method. The mesh setup, output power, voltage, current, and core loss are also presented. Various output parameters of the PMLG for two different temperatures are compared. By observing the characterization of the PMLG, N48H permanent magnet and M4-Carlite magnetic core are selected and proposed for the design. Simulation results show that the proposed PMLG can generate 2.85kW more output power while minimizing the core loss significantly.

In this paper, a method of winding optimization of the linear generator is proposed to increase the electrical power generation from the oceanic wave. A linear generator is designed in the ANSYS/Maxwell environment to analyze the proposed winding optimization method. The electrical and magnetic properties of the generator are extensively analyzed. The cross-sectional area and the number of turns of the copper conductor are optimized to maximize the output power. Load characteristics are also considered for different conductor sizes and turn numbers to determine a suitable operating point. A cooling system is also incorporated in the optimized linear generator to extract the thermal energy produced during the operation, which eventually enhances the electrical power generation. It is found that the optimized linear generator finally generates around 42% more electrical power compared to that of the conventional one. Therefore, the volumetric power density of the linear generator is noticeably increased with the proposed optimization method that also results in the minimization of material cost of the generator. A downscale prototype of the linear generator is constructed in the laboratory. It is expected that the proposed winding optimization method can be used in designing other linear generators.

Matrix converter applications in the power electronics field eliminate the common practice of reactive power storage in the system. Due to its universal converter applicability, the Single Phase Matrix Converter (SPMC) is among the most widely used matrix converter configurations. Operating as a universal converter means that the SPMC can be used as a frequency changer, an inverter, a rectifier, and a chopper. The SPMC topology consists of four bidirectional switches that allow reverse blocking and bidirectional current flow. This paper presents the implementation of SPMC as an AC/AC converter with passive load conditions. The output of SPMC is synthesized using the Sinusoidal Pulse Width Modulation (SPWM) technique to calculate the switch duty ratio. The modelling and simulation of SPMC are carried out using MATLAB/Simulink software, and the results are discussed. Further testing was conducted with the input generated from a point absorber wave energy converter simulated in ANSYS to validate the ability of the SPMC as an AC/AC converter model.

Permanent magnets (PMs) power several industrial technologies that enable our modern society and high standards of living. As such technology becomes more advanced and widespread, the demand for PM-based motors and generator increases, and thus the demand for PMs themselves increases. Additive manufacturing (AM) could be an attractive method for manufacturing PMs, as it minimizes the use and waste of critical, supply-limited rare earth materials and enables near-net-shape printing of complex geometries. In this work, the critical roles that PMs play, as well as the challenges and difficulties in utilizing them, are discussed. The conventional manufacturing processes for PMs are explored, and their advantages and disadvantages are highlighted. The advantages of AM are briefly introduced. Then, a survey of the major PM materials is provided, which introduces the major magnet families and summarizes their material properties. The benefits and advantages of AM over conventional methods in creating PMs are explored in detail. After that, the AM processes that have been used to manufacture PMs are reviewed, and the AM research efforts relating to each type of these PMs are explored. The magnetic and thermal properties of AM of PMs are reported in detail. For example, printed Nd2Fe14B magnets with suitable polymers can be operated at as high as 175°C with improved corrosion resistance. There is a focus in this paper on the use of AM PMs on wind turbine generators and large electrical machines across all sections. The future outlook of the use of AM processes for PM manufacturing is also provided.

In compliance with the green energy policy, mitigation from high fossil fuel dependency is becoming a new objective for most countries, including Malaysia. Wave energy is among extensively explored renewable energy relatively clean, sustainable, and inexhaustible resources. To this day, neither definite wave energy technology nor widely available commercial wave farm supplying the grid has existed. Therefore, wave energy harvesting is the most compelling solution, especially in regions where the possibility of grid connection is low in the nearest future. Like other renewable energy, the voltage amplitude and frequency generated from waves are unstable and may vary continuously. This uncertainty has created energy transfer challenges since the grid requires a stable and uninterrupted energy supply. Therefore, power electronics devices are employed to modulate the controller circuits’ pulse width. Further understanding of the relationship between wave energy conversion technology and its power conversion, particularly for nearshore applications, is summarized. This work also discussed selected wave energy conversion research and power conversion system implemented and studied in Malaysia. Finally, this review can provide extensive overview and broad understanding into power conversion system for Wave Energy Conversion, especially for nearshore applications.
