REACTIVE POWER COMPENSATOR Russian patent published in 2012 - IPC H02J3/18 

FIELD: electric engineering.

SUBSTANCE: application: in electric engineering. The reactive power compensator includes three-phase voltage divider and single-phase current transformers connected to power system phases. Voltage sensors are connected to three-phase voltage divider output. The reactive current sensors are coupled with single-phase current transformers output. The outputs of reactive current sensors and voltage sensors are coupled with a comparison elements input with their output being connected to inverters. The inverter outputs are linked with control signal generators with their inputs being connected with differential amplifiers, and their inputs are connected to the power modules coupled with capacitive filters having their outputs connected to power system phase.

EFFECT: increased response, improved performance and reduced weight and dimension characteristics.
