波浪能发电的能量密度高于风能、太阳能等一些可再生能源。然而，由于波浪具有不规则的往复运动，很难将波浪能转化为电能，这限制了波浪能的广泛应用。本文提出了一种将波浪能转换成电能的新机制。它被称为“直接链接”机构，由浮标、齿条和小齿轮组成。由于其简单的负载传递路径，预期能量转换效率高于通常的波浪能转换系统。所提出的系统的表面永磁同步发电机被设计成具有不同的极数。通过动态模拟计算了考虑潮之岬波出现概率的电输出特性。结果表明，所提出的系统的转换效率显着提高，从一个传统的系统。
The energy density of wave power is higher than some renewable energy sources such as wind and solar energy. However, because waves have an irregular reciprocating motion, it is difficult to convert wave power into electricity, and this has restricted the widespread use of wave power. In this paper, a new mechanism to convert wave power into electricity is proposed. It is referred to as a “direct-link” mechanism consisting of a buoy, rack, and pinion. Because of its simple load transfer path, it is expected that the energy conversion efficiency is higher than that of the usual wave power conversion systems. Surface permanent magnet synchronous generators for the proposed system are designed with different numbers of poles. The electrical output characteristics considering the appearance probability of the waves in Shionomisaki are calculated by a dynamic simulation. It is shown that the conversion efficiency of the proposed system is remarkably improved from that of a conventional system.
