DEVICE FOR CORRECTION OF SHAPE OF VOLTAGE CURVE Russian patent published in 2016 - IPC H02P9/10 H02P9/14 H02P9/30 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and can be used in devices for controlling voltage of AC generators of autonomous electric power sources. Technical result is reducing degree of non-sinusoidal voltage waveform. Voltage waveform correcting device comprises a booster transformer (1), first single-phase half-wave rectifier (2), second single-phase bridge rectifier (3), driver limiter (4), low-pass filter (5), first (6) and second (36 ) analogue-to-digital converters (ADC), first (7), second (8) and third (9) short-pulse formers, NOT gate (10), OR gate (11), RS-flip-flop (12), delay element (13), first (14), second (15) and third (16) memory registers, numerical comparator (17), summing counter (18), generator (19) of stable pulses, subtractor (20), digital-to-analogue converter ( DAC) (21), three-dimensional memory unit (22), first (23), second (24), third (25), fourth (26), fifth (27), sixth (28), seventh (29) and eighth ( 30) electronic switches, load (31), source bus (32) and switch (33) formed of electronic keys (23…30). Buses (32) are connected to AC generator (34) with system (35) to control excitation.

EFFECT: device with high accuracy provides compensation of distortion of AC voltage waveform.
