Simple sliding mode applied to the three-level boost converter for fuel cell applications

This paper discusses the concept of simple sliding mode to resolve the problem of control of a three-level boost converter for fuel cell applications. Simple sliding mode involves simple sliding surfaces; they are a class of surfaces that reveals the dispersion of nonlinear stabilizing surfaces for a given nonlinear MIMO system. In the case of the three-level boost converter, simple surfaces have a quadratic form. Recall that a three-level boost converter is an alternative topology of the conventional boost converter but it experiences overt it some significant advantages namely an improved power ratio and minimized current and voltage ripples.
