This letter addresses the various issues concerning the implementation of a pulse-width modulation (PWM) based sliding mode (SM) controller for boost converters.The methods of modelling the system and translation of the SM control equations for the PWM implementation are illustrated.Experimental results show that the proposed control scheme provides good voltage regulation and is suitable for common DC-DC conversion purposes. The derived controller/converter system is suitable for any changes on line voltage and parameters at input keeping load as a constant.
