摘要：This paper presents the discussion of multi-pulse improved power quality ac-dc converter configuration,comparative factors and selection of specific. Reliable low distortion DC supply is a prime concern for medium andhigh voltage applications. Multilpulse converters is one of the popular device that furnishes low ripple DC output withthe benefit of direct conversion from AC supply. The three-phase multi-pulse AC to DC conversion system have aphase-shifting transformer and a three-phase source. Every such type of converter provides a 6-pulse AC to DCconversion system, that’s why in order to produce more sets of 6-pulse systems,a uniform phase-shift is required and hence with proper phase-shifting angle, 12, 18, 24, 30, 36 and higher pulsesystems have been produced. This paper describes the comparative analysis and design of even group combinationsnamely 6, 12 and 24 pulse converters with MATLAB simulations. The performance improvement of multi-pulseconverter is achieved for total harmonics distortion (THD) in supply current, DC voltage ripples and form factor. TheInput A.C current waveform and the DC output waveform and harmonic analysis has been observed.
