FIELD: conversion equipment. SUBSTANCE: three-phase voltage inverter has main thyristors 1-6 with reverse diodes 7-12. Switching thyristors 15-20 are connected in parallel opposition and are linked to main thyristors. By insertion of two supplementary chokes 26, 27 and of two supplementary thyristors 28, 29 transfer of auxiliary stages of recharging of switching capacitors 21, 22 from circuits with switching and main thyristors into circuits with supplementary chokes and thyristors is ensured. EFFECT: increased operational reliability. 2 dwg
