SYNCHRONISING DEVICE FOR POWER SUPPLY SYSTEMS WITH NEUTRAL WIRE Russian patent published in 2014 - IPC H02M7/00 H02M7/12 

FIELD: electricity.

SUBSTANCE: claimed device includes auxiliary busbars A₂, B₂, C₂, six summators and two adaptive non-periodic first order filters that ensure filtration for the three-phase voltage system at minimum required quantity of non-periodic filtering stages based on the generalised vector image of the three-phase sequence.

EFFECT: providing stable synchronising pulses for thyristor rectifier control systems when distorting harmonic components are available in the supply mains with less amount of non-periodic filtering stages.
