A CONSTANT-PRESSURE HYDRAULIC PTO SYSTEM FOR A WAVE ENERGY CONVERTER BASED ON A HYDRAULIC TRANSFORMER AND MULTI-CHAMBER CYLINDER

A Constant-Pressure Hydraulic PTO System for a Wave Energy Converter Based on a Hydraulic Transformer and Multi-Chamber Cylinder

This paper presents a constant-pressure hydraulic PTO system that can convert stored pressure energy into electrical energy at a stable speed through hydraulic motors and generators.A multi-chamber cylinder can be connected to the main power generation circuit by check valves, and the motor displacement can be controlled by a fuzzy controller to ma
