PWM Based Sliding-Mode Control For a DC-DC Boost Converter

Abstract

 DC to DC converters iscommonly applicable the many applications, fluctuating from computer to remedial electronic systems, devices of consumer electronic devices, spaceships,telecommunication and other power systems equipment’s. The advantage of converters in the electricity system is to continue the required production voltage and to control the parameters according to variation in load. Converter arecontrol  output voltage from the converter are necessary to control  duty of cycle of semiconductor device used in the system. The application of nonlinear control, is controlled  thesliding-mode (SM) control  is a variable control structure system theory .This Variable structure systems are fleshly structures  which is chang the during time of  structure control rule.When this structure is changing they are determine the system current state. Switching action is present, thenpower supplies of switched-mode is generally variable structured systems. Hence sliding-mode controller is controlling the dc to dc boost converters.
