dc.descriptionABSTRACT: This paper proposes a new sliding surface for controlling a Semi-Bridgeless Boost Converter (SBBC) which simultaneously includes Power Factor Correction (PFC) and DC bus regulation. The proposed sliding surface is composed of three terms: First, a normalized DC voltage error term for controlling DC bus and rejecting DC voltage disturbances, normalization was performed for increasing system robustness during start-up and large disturbances. Second, an AC current error term for implementing a PFC scheme and guarantying fast current stabilization during disturbances. Third, an integral of AC current error term for increasing the stability of the overall system. Also, an Adaptive Hysteresis Band (AHB) is implemented for keeping constant the switching frequency and reducing the THDi. The proposed sliding surface was validated by means of sliding mode conditions and Lyapunov stability criteria. Simulations for comparing performance were performed between: a cascade PI control, a hybrid PI-Sliding Mode Control (PI-SMC), and Sliding Mode Control (SMC) with the proposed surface; additionally, it is presented an stability analysis for the proposed surface in start-up and under large perturbations. It is also presented experimental results for PI-SMC and SMC implemented in a SBBC prototype. The proposed surface implemented in the SMC presents the best dynamic behavior removing DC over voltages and responding faster under DC voltage changes or DC load current perturbations.
