“…2, this work considers the design of two sliding-mode control laws for the and variables. Recalling the results of previous studies [10]- [17], a first sliding-control law will be designed to control the full bridge switch of the buck stage (control variable ) for tracking an external sinusoidal reference, thus providing a dc-ac conversion. A second law will be designed to control the dc-dc boost stage (control variable ) in order to set the intermediate voltage at a large enough value to ensure a global ac output voltage amplitude to dc input voltage step-up ratio.…”

“…Alternatively, transformerless step-up conversion topologies could be considered. Nonetheless, although sliding-mode control has been successfully applied to switching dc-dc converters exhibiting a step-up voltage conversion ratio such as the boost converter [8], [22], the coupled-inductorČuk converter [9] and the boost-buck converter [10], [11], preliminary studies have shown the analytical difficulties in applying sliding-mode control techniques to these power stages for a dc-ac step-up conversion ratio [20], [21].…”

Abstract-This paper presents a sliding-mode control design of a boost-buck switching converter for a voltage step-up dc-ac conversion without the use of any transformer. This approach combines the step-up/step-down conversion ratio capability of the converter with the robustness properties of sliding-mode control. The proposed control strategy is based on the design of two slidingcontrol laws, one ensuring the control of a full-bridge buck converter for proper dc-ac conversion, and the other one the control a boost converter for guaranteeing a global dc-to-ac voltage step-up ratio. A set of design criteria and a complete design procedure of the sliding-control laws are derived from small-signal analysis and large-signal considerations. The experimental results presented in the paper evidence both the achievement of step-up dc-ac conversion with good accuracy and robustness in front of input voltage and load perturbations, thus validating the proposed approach.Index Terms-boost-buck switching converter, dc-ac step-up conversion, sliding-mode control.
