Power factor corrector

Abstract

One of the problems of power electronics engineering is the solution of a problem of electromagnetic compatibility of converters with a network. The nonsinusoidal curve shape of a current consumption reference for the majority of modern converters of electrical energy causes distortion of a line voltage, that degrades activity of other customers, results in increase of power dissipation in wires, transformers and other load-bearing elements. The problem of formation of a sinusoidal input current can be solved, using a boosting converter. The paper describes the design of such a 2 kW converter in which one of the quasisinusoidal currents is reshaped. It is intended for use a source of stabilised constant voltage, or as a power factor corrector.
