A method for controlling Vienna Rectifiers

摘要

The present invention relates toA method for generating a current set point value for a charging device connected to a power network;At least one voltage is measured (61) andMeasured voltage (vmes) and electric pulsation of power network ω Depending on the value of G)Filtered voltage (vftr) is calculatedFilter processing step (62) andAccording to the at least one measurement voltage and at least one filtered voltage (vftr)The frequency (FG) and amplitude (VG) of the measured voltage are estimated (63) andAccording to the measured voltage (vmes) and the filtered voltage (vftr),An integrated step (64) is calculated for the integrated voltage (VCS) andAccording to the integrated voltage (VCS) and the estimated amplitude (VG)Includes step (65) for generating a current set point valueRelated to the method.Diagram
