Analysis of Boost Converter Using PI Control Algorithms

Abstract

This paper explains about the boost converter and control algorithm to reduce harmonics. For the improvement of the functionality of the boost converter there are many methods available among which I consider PI controller in voltage mode control path. Initially I discussed the basic function of the boost converter. Then I derived the transfer function of the complete system. Then I considered model and simulate into matlab without PI controller. Finally I used PI controller in which the values of ࡷ࢖ and ࡷ࢏ has been derived using the Ziegler-nichols method and loop shaping method. At last the output response of the both methods is compared and conclusion made upon that comparison.
