The purpose of this paper is to evaluate the possibilities of hybrid excitation synchronous generator (HESG) for wind applications. In HESG, excitation flux is created by both permanent magnets and excitation coils, so the output voltage can be controlled by the DC excitation field. For isolated loads, it is then possible to use the simplest and the most reliable wind generator architecture composed only by a HESG, a rectifier and a DC/DC converter to control the excitation flux [3]. In this paper, the wind generator architecture is presented, modeled and simulated to demonstrate the interest of HESG for wind applications.
