MACHINE-VALVE GENERATOR OF DIRECT CURRENT

摘要

FIELD: electricity.SUBSTANCE: machine-valve generator of direct current (MVGDC) comprises electrical alternating-current machine with two groups of galvanically isolated three-phase armature winding, two three-phase rectifiers as per bridge scheme, and current transformer. Current transformer is single-phase with two in-series windings, which connection point forms the first output of the machine-valve generator. the first output leads of three-phase rectifiers of the same polarity are connected to ends of windings of single-phase current transformer, the other output leads of three-phase rectifiers of the same polarity are connected and form the second output lead of the of the machine-valve generator. Each of three-phase armature windings is connected to inputs of one of three-phase rectifiers. Groups of galvanically isolated three-phase armature windings are shifted spatially in regard to each other per angle of ?/6.EFFECT: reduced weight and dimensions of the system.2 dwg
