FIELD: power engineering.
SUBSTANCE: invention relates to power converter apparatus control systems and can be used as a synchronisation apparatus in three-phase controlled bridge rectifiers and for synchronisation in digital and analogue valve converter control systems. The substance of the proposed method and apparatus for synchronising a voltage converter control system consists in forming an initial synchronising voltage as a result of two-level division of the phase voltage half-wave and comparison thereof, synchronising digital (analogue) valve converter control systems and three-phase controlled rectifiers.
EFFECT: claimed method and apparatus increase the accuracy of voltage synchronisation, simplify the synchronisation circuit of a voltage converter control system, and increase the operating reliability thereof.
