N2 - Modeling and simulation are important parts in analysis and design of electrical circuits. Nowadays, with the revolution in energy and penetration of renewable energy resources to the power grid, the power converters play vital role in power systems. The mathematical models of these converters are nonlinear due to switching behavior. In this paper, we consider controller design for boost converters. The DC-DC boost converter is modeled using small signal analysis where the duty cycle and the voltage are the control and output variables respectively. A controller for the linearized model of the boost converter is designed to achieve constant DC output voltage irrespective of load variation. The transfer function of the converter is derived and employed to design a PI controller using the root locus technique. The quality of the designed controller is tested in the MATLAB/SIMULINK environment. Simulation results of the closed-loop system are obtained for source and load disturbances. To validate the proposed control methodology, the designed controller is tested on the actual nonlinear converter using SIMULINK. The simulation results show accepted performance of the converter in the presence of disturbance.
