Description
Summary:The effect of load variations on the stability of the open-loop DC-DC boost converter is investigated in this paper. Mathematical model of boost converter is derived using state-space averaging technique and perturbation technique presented in this paper to linearize the small AC components. The calculations have been done to ensure the converter is operates in continuous conduction mode (CCM). The open-loop system of boost converter is developed using MATLAB/Simulink software along with the simulation results. The changing of load parameter has been studied so that the stable design of boost converter can be carried out by following a systematic procedure. From the simulation results, it can be shown that load variation gives significant effect on the transient response of the converter.
