Abstract :
This paper describes an improved topology of a linear permanent magnet generator for sea wave energy harvesting and presents an electrical model for analysis of this generator. The electrical model is established based on the magnetic equivalent circuit of the machine. This model can be used to design a power electronic interface for capturing maximum power at the resonant frequency of a sea wave. Validity of the model is verified via comparing the calculated inductance of the machine with that of obtained from numerical analysis based on finite element method.
