Abstract :
DC/DC switching converters have been used in many applications in recent years. The sliding mode control based on VSS (variable structure system) theory has been examined for all switch mode converter types, whilst current mode (CM) control scheme is particularly applied to DC/DC converters. In this paper, a new control strategy by compromising both schemes and derivation of dynamic current reference is proposed, analyzed and simulated. Moreover, considerations for realization with DSP controllers are addressed
