Implementation of PI Controller for Boost Converter in PV System

This paper describes the implementation of Proportional Integral controller for boost converter in Photo Voltaic system. The reason behind using PI controller is it removes the delay and provides fast control. There are many types of controller that can be used to implement the elegant and effective output. The PI stands for Proportional and Integral Controllers, which are designed to eliminate the need for continuous operator attention, thus provide automatic control to the system. In this paper the PI controller is used and the Kp and Ki gain value is calculated by using trial and error method. This paper is focusing on implementing PI controller to boost converter. The boost converter is mainly used for voltage step up operation. So, the output voltage is greater than the input voltage. The PWM signal generator is used for commutation purpose in boost converter. The boost converter model is simulated by using MATLAB/SIMULINK. The boost converter maintained the constant output voltage in the load
