Design of a Moving-Coil Linear Generator for Marine Energy Conversion

Abstract:

The Inertial Sea Wave Converter is a device that uses the effect of a gyroscope to convert wave energy into electric energy. It is equipped with two Linear Tubular Permanent Magnet Generators. This paper describes the design and optimization processes for a moving-coil linear generator to be installed on the Inertial Sea Wave Converter. FEM Analysis has been performed to validate the design and to optimize forces and generated power. A Power Factor Corrector has been developed as frontend electronics.
