Design Methodology for Optimized Control of High-Power Quadratic Buck Converters Using Sliding Mode and Hybrid Controllers

This paper introduces a novel design methodology for optimizing the control of high-power quadratic Buck converters using a Sliding Mode Controller (SMC). The proposed methodology focuses on addressing the non-linearities and dynamic challenges inherent in such converters, offering a systematic approach to controller design that enhances both stability and efficiency. The SMC is rigorously validated through dual rapid prototyping methods, Hardware-in-the-Loop (HIL) and Software-in-the-Loop (SIL), to ensure robust performance across diverse operating conditions. Additionally, a hybrid control strategy is explored, integrating traditional PID control with the SMC to leverage the strengths of both approaches. A comprehensive stability analysis, including root-locus diagrams, further confirms the reliability of the proposed controller. Comparative analysis against conventional PID control demonstrates the superiority of the SMC, particularly in managing complex operational scenarios. This work provides a significant advancement in the control of quadratic Buck converters, offering a comprehensive framework for implementing reliable and efficient control strategies, and paving the way for future applications in high-power systems.
