METHOD OF ELECTRIC ENERGY QUALITY IMPROVEMENT AND ASSOCIATED DEVICE Russian patent published in 2008 - IPC H02J3/01 H02J3/26 

FIELD: power production.

SUBSTANCE: when non-sinusoidal shape of supply voltage is decreased, electric power is distributed between electronic devices distorting the shape of supply voltage and electronic devices improving the shape of supply voltage during the semi-wave of supply voltage. Device is connected in parallel with consumers introducing distortions of voltage shape. Main voltage is supplied to the device input. Device includes serial connection of phase-shifting chain, control pulse shaper, dc power supply and power switcher, which connects consumers improving the shape of supply voltage to the mains at a certain period of time.

EFFECT: improvement of supply voltage shape and simplification of device design.
