Adaptive Backstepping Control of PWM DC-DC Boost Power Converter Considering Parasitic Elements Effect

On the basis of the continuing need for reliable converters in order to interface low voltage dc sources to medium and high voltage ac systems. This paper presents a recursive adaptive backstepping design methodology and Lyapunov theory to control dc-to-dc switched mode boost converter taking into consideration the effect of parasitic elements. Although there have been many developments in this area, this method considers the effects of parasitic parameters that are uncertain or change occasionally. Designed controller was simulated using MATLAB/Simulink and results indicate the stability and fast response under a possible variation in the load or input voltage.
