Description: This paper discusses the impact of using 3-phase and multipules converter circuit commonly found in unity power factor at
input AC mains and regulates output voltage.3-phase thyristor rectifiers have been used in industries for obtaining a variable DC
voltage, but they have a problem of including large lower-order harmonics in the input currents. For high-power applications, a 12-
pulse, 18-pulse and 24-pulse configuration is useful for reducing the harmonics, but it still includes the (np±1) th (n: integer, p: pulse)
harmonics. In this paper present the rectifiers are using the MATLAB/SIMULINK simulation model and several common conditions
will be simulated to compare their harmonic levels. Platform: |
