Single-phase AC rectifier with high power factor

This paper analyzes the known methods of ensuring electromagnetic compatibility of average single-phase AC consumers having semiconductor rectifiers, thus having nonlinear I-V curves, with a power supply network. The traditional method of single-phase AC-DC conversion for domestic needs and industrial automation is based on the use of common bridge rectifiers with a capacitive load having low power characteristics that are to be improved by additional correcting devices. Reconsideration of the way of interaction between a rectifier and its smoothing capacitor used as an energy accumulator gives additional possibilities for increasing power characteristics of power sources with such rectifiers and improving electromagnetic compatibility with a single-phase AC supply network.
