A New Current Control Strategy of Maximizing The Generated Power From a Doubly Fed Induction Generator System

Switched reluctance generator (SR Generator) has various desirable features which include simple and solid structure, easiness of maintenance, small moment of rotor inertia and low cost. However, the SR generator has not been put into practical use widely because an optimum design of SR generator has not been fully considered. Furthermore, the excitation circuit of conventional SR generator utilizes an asymmetry half bridge converter (AHBC) which has complicate circuit. In this paper, we present some considerations on an 8/6 SR generator excited by a suppression resistor converter (SRC) which is consist of half number of switching devices for the AHBC. The operating characteristics of the SR generators were discussed based on FEM analysis and experiments
