ELECTRICALLY-DRIVEN PULSED PHASE SHIFTER Russian patent published in 2020 - IPC H02K47/22 H02K1/24 

FIELD: electromechanics.

SUBSTANCE: invention relates to the field of electromechanics and can be used in systems of pulse-phase control of technological electronic devices, for example thyristor rectifiers. Electromachine pulse phase shifter comprises ferromagnetic cores of stator and rotor with windings on them. Stator core accommodates a three-phase input winding. Rotor is coaxially inserted into stator with possibility of rotation. Rotor core is made in the form of cylindrical pipe divided in axial direction into three parts by non-magnetic gaps and connected inside the pipe by rods forming three-beam star. Rods are made from material with rectangular magnetic characteristic. Output winding of the rotor is made in the form of coils on rods. This provides both control of phase shift between input voltage on stator winding and output voltage on rotor winding, and optimum shape of output voltage in form of short pulses.

EFFECT: technical result consists in improvement of reliability.
