A novel robust sliding mode controller for Half-bridge converter

This paper proposes one novel sliding mode controller for the Half-bridge converter to reduce the line and load disturbance. Based on the bilinear model of the Half-bridge DC/DC converter, the small signal model and the design consideration of the sliding mode controller for this converter are deduced and presented. The controller is simply implemented in the analog controller board. The validation of the controller is verified both by theory analysis and experimental results. By applying the novel sliding mode controller, the Half-bridge converter can achieve good transient response.
