Abstract

This paper concerns the electromechanical model for a pendulum-type wave energy converter (PWEC). By introducing a based-excited mass-spring-damper, the motion of PWEC is divided into two parts: the motion of floating body and the relative motion of the pendulum and floating body. The electromechanical model involves the relative motion. Based on the electromechanical model, the circuit optimization is researched in frequency domain. The simulation results show that the device harvests plenty of power when the excitation is in close proximity to natural frequency, and the output power will decay sharply when the excitation is away from natural frequency. The optimal active power is obtained when the total reactance is zero.
