Patents by Inventor Valery Anatolievich Boshnyaga

Valery Anatolievich Boshnyaga has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 4013942
    Abstract: A phase shifter having two multiwinding transformers. The primary windings of the like phases of different transformers are connected in series and arranged in a three-phase system. The secondary windings of unlike phases of different transformers are interconnected and form two three-phase output voltage sets. Each transformer has control windings connected to respective switching devices. Actuation of a respective switching device provides for changing the phase angle between the three-phase output voltage sets from 0.degree. to 120.degree. or 180.degree..

  • Patent number: 3975673
    Abstract: A phase shifter comprises a three-phase transformer and a reactor to obtain two three-phase output voltage sets, the phase angle therebetween being set equal to 0.degree., 120.degree. or 180.degree.. Depending on the load, the proposed phase shifter makes it possible, with its transformer or reactor control windings shorted, to switch over a controlled power transmission system of high power-carrying capacity from operation with a phase angle of 0.degree. to operation with a phase angle of 120.degree. or 180.degree..
