ADAPTIVE INTEGRATING SYNCHRONISATION DEVICE Russian patent published in 2014 - IPC H02M1/08 H02M1/12 

FIELD: electricity.

SUBSTANCE: invention relates to the field of electric engineering and may be used in control systems for alternating- and direct-current thyristor converters as well as active front ends. The synchronisation device represents a closed integrating self-oscillating system with the scheme of frequency-amplitude correction. The adaptive integrating synchronisation device comprises the first summator (1), an integrator (2), the second summator (3), a relay element (4), three identical synchronising circuits (5)-(7), a logic element (8) of 3 OR function, period-to-voltage converter (9), the third summator (10), an amplitude modulator (11) and reference voltage source (12).

EFFECT: improving dynamic accuracy in the area of low synchronizing depth values less than the level of 2,0 due to change in the line voltage period T_C during time T_C/6 or 60 electrical degrees.
