Resumo

This article presents the dependence of the power factor of an ac downconverter on the component parameters of an input LC filter. The obtained results allow filter parameters to be selected at which the high power factor of a converter in operating control range is provided. Analysis was carried out for the pulse-width algorithm of regulation of the voltage and load at which an induction electric motor was used. Results of analysis were confirmed by computer simulation and experiments.
