摘要：

This study presents a permanent magnetic linear generator based system for ocean wave energy harvesting applications. The use of linear generator as energy converter enables a direct coupling of the motion of the buoy to the energy harvesting system. Mathematical model governing the system is presented; frequency domain analysis reveals that conversion rate varies with respect to load resistance. Detailed numerical results including average power, system efficiency are obtained using MATLAB (R), Simulink (R), SimPower-Systems (R). The optimum load value is found based on the fully physics simulation of the system. To this end, current control application to the boost converter is presented. Presented results show that the controller successfully regulates the current. The proposed system is designed to operate with the optimum load value.
