Analyses of Energy Efficiency of Interleaving in Active Voltage-Source Rectifier

The paper presents the results of the study of energy parameters of high power multi-bridge active rectifiers in the interleaving mode. Obtained the regulating characteristic of output voltage in active rectifier in rectification mode and recuperation mode. Developed Matlab / SymPowerSystems models of multi-bridge active rectifiers with a different number of parallel bridges and different PWM frequencies in interleaving mode. According to the performed modeling were analyzed spectrum of input current harmonic and defined power losses in supply grid caused by higher current.
