METHOD OF CONTROL OVER THREE-PHASE-TO-CONSTANT VOLTAGE CONVERTER Russian patent published in 1994 - IPC

FIELD: conversion equipment. SUBSTANCE: method lies in formation of two sequences of controlling pulses synchronized with voltage of network with frequency equal to triple frequency of network and in their feeding to controlling inputs of keys. Two additional sequences of adjustment pulses are also formed to provide for adjustment of output voltage of converter. In compliance with them additional connections of keys are introduced. Voltage can be controlled in three ranges depending on type of formed sequence of adjustment pulses. EFFECT: expanded control over output voltage. 2 cl, 5 dwg
