	abstract = "Blade-tip-speed ratio feedback control is applied to a wind turbine driven, grid connected, three phase, induction generator whose wound rotor winding is connected to a rectifier via slip rings. Power from the rotor winding flows through the rectifier to a switch-mode, stepup, DC to DC converter to re-charge a bank of batteries. The switch in the DC to DC converter has a variable duty cycle, and this design feature is used in a feedback control loop. A dynamic model of the complete system is presented along with simulation results.",
