Converters are widely used in many fields specially Distributed Generation applications. Because of the non-linear and the uncertain characteristics of DC-DC converters, Sliding Mode Control (SMC), which is robust against uncertainties and disturbances, is implemented in a full-bridge converter in order to control the converter output by varying the duty cycle of the converter. The proposed method is explained and formulated using state-space average model of the fullbridge converter. Additionally, the effects of changing the design parameters of the introduced sliding mode controller in tracking performance and tracking are discussed. Moreover, the system behavior during load and source sudden changes is analyzed. High performance and tracking accuracy of the system under parameter variation are confirmed appropriately using simulations.
