FIELD: electricity.
SUBSTANCE: synchronisation device comprises the first (1), second (2), third (3), fourth (4), fifth (5) and sixth (6) comparators, three units (7), (8), (9) of logical function "2AND", buses of phases A, B, C. For this purpose three additional comparators perform pairwise comparison of phase voltages A, B, C with further generation of logical synchronisation signal "1" on the basis of logical function "2AND" by comparison of output signals of the main and additional comparators.
EFFECT: increased accuracy of operation under conditions of unstable phase voltages.
