AC VOLTAGE NORMALIZER Russian patent published in 2017 - IPC H02M5/12 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and can be used for keeping AC voltage within preset limits. Assigned task is solved by fact, that AC voltage normalizer includes input and output terminals, transformer with primary and secondary windings, latter is connected by first output to first input terminal, and by second output is to first output terminal, four switches connected by bridge circuit, bridge circuit first diagonal includes transformer primary winding, one of bridge circuit second diagonal outputs is connected to second input terminal, which is also connected to second output terminal. According to disclosed invention, normalizer is equipped with current limitation unit with shunting switch, two hysteresis units and control unit, bridge diagonal second output is connected to first input terminal via current limiting unit, parallel to which current limitation unit shunting switchboard is connected, hysteresis units outputs are connected to control unit input, and control unit outputs are connected to switches control inputs.

EFFECT: disclosed invention task (technical result) consists in improvement of device operation reliability with provision of preset control parameters.
