Abstract

The subject of this paper is a hysteresis current control method of a three-phase 6/4 Switched reluctance generator (SRG) based on the nonlinear inductance model and electromagnetic field finite element analysis (FEA) to be used in wind energy applications. This work is intended to show the nonlinear electromagnetic characteristics of SRG and the power converter circuit which is composed with asymmetric half-bridge topology. Two control strategies are revealed: current chopper and angle position controls. SRG and its behavior, modeling and Simulations results are presented. It was analyzed the characteristics of the SRG, simulation results prove that the generator can achieve different output characteristics under different rotational speeds, which confirms the effectiveness of the designed system.
