This paper is concerned with the design of single-phase, three-level inverters for wind power system with double-winding permanent-magnet synchronous generators. The rotor of a typical wind turbine rotates at a speed of 20-200 rpm in conventional wind power plants the generator is coupled to the turbine via a gear so that it can typically rotate at a speed of 1000 or 1500 rpm the wind power plant can be simplified by eliminating the gear and by using a low-speed generator, the rotor of which rotates at the same speed as the rotor of the turbine. Control of wind turbine driven permanent magnet synchronous generator a thesis submitted in partial fulfillment of the requirements for the award of the degree of.
