1. Wave Energy Conversion : Linear Synchronous Permanent Magnet Generator
Abstract : This thesis studies the electric aspects of a linear synchronous permanent magnet generator. The generator is designed for use in a wave energy converter, which determines the fundamental requirements of the generator. The electromagnetic properties of the generator are investigated with a finite element based simulation tool. READ MORE

4. Design of Direct-driven Permanent-magnet Generators for Wind Turbines
Abstract : This thesis presents an investigation of how a direct-driven wind turbine generator should be designed and how small and efficient such a generator will be. Advantages and disadvantages of various types of direct-driven wind turbine generators are discussed, and a radial-flux permanent-magnet generator connected to a forced-commutated rectifier is chosen for a detailed theoretical investigation.
