dc.description.abstractPower electronics devises which are used by the power industry in the past two decades are increased. Which are the main source of harmonic in now a day. In this the simulate -pulse converters are developed in MATLAB/SIMULINK for improving power quality by reducing harmonics in ac main. We have also improved the power factor of input and ripple factor of dc output and analyzed the effect of source inductance on THD, ripple factor and input power factor. The simulation of 12-pulses, 18-pulses and 24-pulses multi-pulse is performed on MATLAB/SIMULINK for R, RL, RC and D.C. motor as load. The THD, ripple factor and input power factor are calculated for 12,18 and 24 multi pulse converters. The primary winding of the transformers is connected in zigzag, while the secondary windings of the transformer are connected to the converter. By choosing appropriate phase shift between the primary and secondary sides of the transformer the lower order harmonica can be eliminated in pair. so, a very high power quality voltage and current waveform can be synthesized. Comparison of THD (total harmonic distortion) in the input current, ripple in the output voltage and power factor of input side is done in this work. Now we can conclude that performance of uncontrolled converters is better than controlled converters. THD and ripple factor is improved as we go from lower pulse to higher pulse. 24-pulse is more economical and gives better results then 18-pulse converter.en_US
