AC VOLTAGE CONTROLLER Russian patent published in 2013 - IPC H02M5/22 

FIELD: electricity.

SUBSTANCE: controller may be used as a stabiliser of a three-phase AC voltage, a transformerless device of AC voltage increase, a controlled source of stable AC voltage and as a device of smooth start of induction motors. The device comprises in each phase two parallel connected AC switches, and also a capacitor connected between AC switches. Its every phase comprises a capacitor, serially connected with an AC switch, to which in parallel a reactor is connected, being in series connected with another AC switch. The proposed AC voltage controller does not have a transformer, which reduces its weight and dimensions parameters.

EFFECT: development of an AC voltage controller with improved weight and dimensions parameters.
