提出了一种用于波浪能应用的线性发生器拓扑结构。发电机拓扑结构的主要意义在于磁体、铜和钢的相对位置的选择，使得定子和永磁体（PM）转换器之间没有磁力。缺乏磁力和发电机拓扑结构的模块化性质使得发电机的制造和组装比传统的铁芯永磁线性发电机更容易。用遗传算法优化方法描述了解析建模技术。提出的拓扑结构被实现到阿基米德波-摆波-能量转换器。为了验证这一概念，建立了一个50千瓦的样机，并给出了空载和载试验结果。
A linear-generator topology is proposed for wave-energy applications. The main significance of the generator topology is that the relative position of the magnets, copper, and steels has been chosen so that there are no magnetic attraction forces between a stator and a permanent-magnet (PM) translator. The lack of magnetic forces and the modular nature of the generator topology make the manufacture and assembly of the generator easier than a conventional iron-cored PM linear generator. Analytical modeling techniques are described with a genetic-algorithm optimization method. The proposed topology is implemented to an Archimedes-wave-swing wave-energy converter. A 50-kW prototype has been built to prove the concept, and the no-load- and load-test results are presented.
