Simulation of Multipulse Converter for Harmonic Reduction using Controlled Rectifier
Three-phase controlled rectifiers have a wide range of applications, from small rectifiers to large High Voltage Direct Current (HVDC) transmission systems. But they have a problem of including large lower-order harmonics in the input currents. For high-power applications, a 12pulse, 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.
