METHOD TO INCREASE QUALITY AND EFFICIENCY OF ELECTRIC ENERGY USAGE (VERSION 1)

摘要

FIELD: electricity.;SUBSTANCE: level of a specified higher harmonics in a power flux picked by a non-linear load is reduced by extraction of its energy in the form of an equivalent energy of sequence of unipolar periodically repeating width-modulated current pulses, by means of a fully controlled pulse-width-modulation rectifier of a transistor type, which is used to control a modulating signal proportional to the current of the specified higher harmonics. The extracted energy of the higher harmonics is disposed of, by means of its usage for supply to a DC load and accumulation in the form of a DC energy.;EFFECT: reduction of higher harmonic components levels in a supplying power system and increased efficiency of power usage.;1 dwg
