This paper presents a complete design and analysis of the commonly used dc-dc converters by using sliding mode control (SMC). The main advantage of the SM controller is that there is no restriction on the size of the signal variation around the operating point. Small as well large signal variations around the operating point are considered. Sliding mode controllers for buck, boost and buck-boost converters have been designed and simulated. Through simulation results, the superiority of the SMC for dc-dc converters is demonstrated. To verify the magnificent power of SMC over other linear control methods a comparative study has been designed by using PID controller.
