Controlled bridge-circuit three-phase rectifiers with an improved power factor

摘要

Mathematical models are constructed of current consumption by fully controlled bridge-circuit three-phase rectifiers. Using a method based on harmonic analysis of the input current curve and the total power components and using a Fortran-basedsoftware developed, both energy characteristics and the first and higher harmonics at the rectifier input are determined It is shown that the proposed methods of controlling the rectified voltage ensure higher energy characteristics than the known methods.
