Abstract :
In this paper the control problem in a buck converter with input filter is analysed by means of sliding-mode control techniques. Starting from a general sliding surface, the coordinates of the equilibrium point are obtained. Subsequently, particular cases are derived leading to stable equilibrium points either with linear ideal dynamics or with ideal load regulation
