Abstract
The investigation of the input current spectrum of the active high-frequency power factor correctors based on a boost converter is conducted. In the MATLAB/Simulink environment the models of correctors, whose control system implements the borderline control method, peak and average current control methods, are built. The corrector, which generates the least electromagnetic interference in the mains supply, was determined. The input current spectrum dependence on the load of the correctors was investigated. The modificated method of corrector control with the suppression of the third harmonic of the input current was offered. References 3, figures 4.
