Abstract

This paper proposes a tubular permanent magnet linear generator (TPMLG) for a wave energy converter. The proposed TPMLG is built with an array of permanent magnets and independent coils. Advantages and disadvantages of the proposed device are determined with experimental and simulated results. A lumped parameter method is applied to analyze the amplitude of induced voltage and magnetic field mathematically. A finite element analysis is employed in the simulation software to obtain the dynamical behavior of these variables. The translator is tested at three different speeds. A prototype is built to confirm the theoretical analysis and simulations. Simulation and experimental results confirm the mathematical relationship between speed and the induced voltage.
