Abstract—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 statespace
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 openloop
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.
