VOLTAGE INVERTER Russian patent published in 1995 - IPC

FIELD: conversion engineering. SUBSTANCE: inverter has bridge with capacitor and complex load connected between diagonal opposite pair of a.c. terminals, saturable reactors inserted in two comphasal arms, and thyristors, in two other arms. Current transformer is connected in series with saturable reactors and has its secondary winding inserted in thyristor control unit. Control system affords consistency between degree of polarity reversal of saturable reactors by reverse current and turn-on moment of thyristor. EFFECT: improved design. 2 dwg
