Design and optimization for the linear switched reluctance generator

Abstract

In this paper, a novel double-sided direct-drive linear generator based on switched reluctance principle is proposed. In order to acquire a higher power density, the optimization of structure parameters for the double-sided linear switched reluctance generator (DLSRG) is carried out. To observe the nonlinear phenomena in SR generator, two dimensional (2D) magnetic static field distributions is obtained. For imitation of real-time operation, transient magnetic field is analyzed by finite element method (FEM). Then through a series of simulation and analysis, a group of appropriate parameters for the DLSRG are obtained. It is expected that the novel direct-drive generator finds its applications in power conversion fields such as wave power utilization.
