METHOD OF AND DEVICE FOR CONVERTING THREE-PHASE AC TO DC VOLTAGE Russian patent published in 1994 - IPC

Abstract RU 2006164 C1

FIELD: conversion engineering. SUBSTANCE: three-phase AC-to-DC voltage conversion method involves rectification of main and auxiliary voltages, summing-up and filtering of voltages obtained. Main voltage is obtained by summing up two variable-polarity pulse voltages with high-amplitude envelopes shifted in phase through 90 deg. and additional voltage is obtained by subtracting from one variable-polarity pulse voltage obtained that has lower amplitude of envelope the other obtained variable-polarity pulse voltage of same envelope amplitude but shifted in phase through 90 deg. EFFECT: improved reliability of conversion. 2 cl, 2 dwg
