DEVICE TO CONVERT AIR FLOW AND TO PRODUCE AC VOLTAGE Russian patent published in 2013 - IPC F03D1/04 F03D7/04 

FIELD: power engineering.

SUBSTANCE: device for air flow conversion and production of AC voltage comprises a base, a mast, a shell and an electric AC voltage generator with blades. The shell is made in the form of a truncated hollow cone. Blades are installed in the inner plane adjacent to the cone top. The device is equipped with at least one linear reversible electric motor, a unit of command input, a sensor of wind speed, a voltage sensor and a controller. The electric motor is fixed with its body in the section of the outer surface of the electric generator body and is coupled with the end of its rotor to the section of the outer end surface of the cone top. The voltage sensor is connected with its input to the output of the electric generator. The controller is connected with its first input to the output of the command input unit, with its second input - to the output of the wind speed sensor, with its third input - to the output of the voltage sensor, with its first output - to the control input of the first controlled key and with its second output - to the control input of the second controlled key. The first controlled key is connected with its input to the output of the AC voltage grid and with its output to the first input of at least one linear reversible electric motor. The second controlled key is connected with its input to the output of the AC voltage grid and with its output to the second input of at least one linear reversible electric motor.

EFFECT: increased output voltage of an electric generator.
