振荡体波能转换器作为一种经济、易于部署的波能转换器，受到越来越多的关注，尤其在为浮标观测和水下传感器网络供电方面具有重要的研究意义。混合型波能转换器，又称组合式波能转换器，能够捕获振动体的多自由度动能。提出了一种带有液压功率输出(PTO)单元的混合式波能转换器的设计方案，并建立了液压PTO回路的数学模型。根据液压回路的数值模拟结果，利用蓄能器可以获得稳定的系统压力和基本恒定的马达速度。液压回路中存在多缸多缸的情况，各缸的相对空间位置会影响系统压力的稳定性。此外，液压系统压力的稳定性还受蓄能器的大小和气缸数量的影响。
As an economical and easy deployment wave energy converter (WEC), oscillating bodies WEC is gained more and more attention, and it has great significance of research, especially on supplying power for buoy observation and underwater sensor network. Hybrid wave energy converter, it also named combined mode wave energy converter, can capture the kinetic energy of multiple degrees of freedom of an oscillating body. This paper presents a design of hybrid wave energy converter equipped with a hydraulic power take-off (PTO) unit, and builds the mathematical model of the hydraulic PTO circuit. According to the result of the numerical simulation of the hydraulic circuit, a steady system pressure and an essentially constant motor speed can be obtained with the help of accumulators. More cylinders than one are applied in the hydraulic circuit, and the relative spatial positions of the cylinders will affect the stability of the system pressure. Additionally, the stability of hydraulic system pressure is influenced also by the size of the accumulator and the number of the cylinders.
