Abstract

For direct wave energy conversion in a two dimensional(2D) way, this paper proposes a planar, direct-drive generator based on switched reluctance principle. The proposed machine has the merit of a simple and robust structure and it is very suitable for the operation under hostile environment in the ocean. This paper first presents the design and construction of the generator. Then, performance prediction of the generator based on three dimensional(3D) time-stepping finite element methods(FEM) and power generation investigation from co-simulation are carried out. Next, preliminary generation current waveforms are inspected by the regulation of turn-on and turn-off positions based on FEM and verified by experimental results. Last, the voltage output waveform of any one axis of motion is also presented.

Key words： Energy conversion switched reluctance planar generator FEM
