Large-Signal Average Modeling and Simulation of DC-DC Converters with SIMULINK

Abstract: In this paper, modeling and simulation of DC-DC converters under SIMULINK environment is presented. The modeling is performed with a buck converter, employing three different control schemes: voltage-mode control, current-mode control, and average current-mode control. The resulted models are a nonlinear average model that can be used to simulate the converter performance under large-signal condition. Experiment on the prototype circuits subjected to a load current disturbance yields the results which are in r… Show more

“…This makes the analysis much more complicated. Because the inductor current is controlled, it is no longer an independent variable [4]. Take Buck converter under current-mode control as an example, it exhibits the characteristics of a first-order system, and the dynamic is dominated by the converter's output capacitor.…”

“…Previously, many techniques have been proposed for modeling of a converter. Large signal modeling produces a non-linear model of the converter [2]. Since simulations shown in this paper are carried out using LTSPICE, therefore a linearized small signal model was used.…”
