Design and analysis of boost DC-DC converter with PI controller

Abstract

This paper covenants owing to the working of PI Controller fed Boost converter. As PI controller removes the delay and offers quick control, it is preferred in this paper. Out of many controllers which provide effective output, PI is chosen which eliminates the necessity for constant operator attention and instinctive control to the system. In the PI Controller, the gains Kp and Ki are calculated by Ziegler and Nichols method. This PI Controller is used as the effective controller for the Boost Converter. In this converter the output voltage is stepped up (increased) for the given input voltage. The PWM Signal generator is used for commutation purpose in the proposed circuit. The Boost converter maintains a constant voltage at the output.
