This system uses a Wound Rotor Induction Generator with it's Stator connected directly to the Mains Supply. A fully reversable PWM Inverter is connected to the Rotor to provide a wide range of Speed Control. At low speeds power is fed INTO the Rotor and at high speeds power is taken from the Rotor and fed into the Mains Supply.
