48 Pulse Converter with PI and PID Controller

This paper presents modelling and simulation of multi pulse AC to DC converter topologies. In this paper multi pulse converter are developed for improving power quality to reduce harmonics in ac main and ripple factor in DC output. The simulation of 48 pulse converter is performed on MATLAB simulink by using universal thyrister. The main focus of this study to minimise (THD) near to zero by use of PI and PID controller. The Thd of dc output are calculated by FFT analysis in matlab and comparative analysis of performance of each controller as PI and PID controller is done in this research paper.
