“…This system allows controlling both DC voltage and AC current; the reference current is obtained from the power balance and the adaptive hysteresis band gives the control signal. The AHB is designed based on current ripple geometry according to Mejía-Ruiz et al [35]. It has two functions: (1) smooth the current zero crossing in order to decrease THD i ; and (2) modify the switching time according to SBBC operation point in order to fix the switching frequency.…”

This paper proposes a new sliding surface for controlling a Semi-Bridgeless Boost Converter (SBBC) which simultaneously performs Power Factor Correction (PFC) and DC bus regulation. The proposed sliding surface is composed of three terms: First, a normalized DC voltage error term controls the DC bus and rejects DC voltage disturbances. In this case, the normalization was performed for increasing system robustness during start-up and large disturbances. Second, an AC current error term implements a PFC scheme and guarantees fast current stabilization during disturbances. Third, an integral of the AC current error term increases stability of the overall system. In addition, an Adaptive Hysteresis Band (AHB) is implemented for keeping the switching frequency constant and reducing the distortion in zero crossings. Previous papers usually include the first and/or the second terms of the proposed sliding surface, and none consider the AHB. To be best of the author’s knowledge, the proposed Sliding Mode Control (SMC) is the first control strategy for SBBCs that does not require a cascade PI or a hybrid PI-Sliding Mode Control (PI-SMC) for simultaneously controlling AC voltage and DC current, which gives the best dynamic behavior removing DC overvoltages and responding fast to DC voltage changes or DC load current perturbations. Several simulations were carried out to compare the performance of the proposed surface with a cascade PI control, a hybrid PI-SMC and the proposed SMC. Furthermore, a stability analysis of the proposed surface in start-up and under large perturbations was performed. Experimental results for PI-SMC and SMC implemented in a SBBC prototype are also presented.

“…Additionally, the CM noise can also be reduced if coupling inductors are used [101] while switching losses can be reduced if a snubber circuit is implemented [63,[102][103][104]. In addition, THD i can be improved if any nonlinear control technique is implemented [11]; the authors in [11] developed a sliding mode control together with PI and an adaptive hysteresis band were proposed to reduce THD i and, at the same time, to improve the dynamic converter response.…”

“…CBP converters implement the Power Factor Correction (PFC) technique that consists of controlling the AC current demanded from the network in such a way that AC current is sinusoidal and in phase with the voltage of the supply network and, at the same time, they perform DC voltage regulation in their output. Basically, CBP converters behave as a resistive load for the electrical network, improving the power quality and overall efficiency and also by helping comply with the harmonic regulation IEC 1000-3-2 [7][8][9][10][11]. Another important aspect is that CBP converters may also avoid the use of active power filters between the power network and loads, which yields a more economic and suitable solution in these kinds of applications [12,13].…”

Power Factor Correction (PFC) single-phase AC/DC converters are used in several power electronics applications as full wave control rectifiers improving power quality and providing high standards of efficiency. Many papers dealing with the description or use of such topologies have been published in recent years; however, a review that describes and organizes their specific details has not been reported in the technical literature. Therefore, this paper presents an extensive review of PFC single-phase AC/DC converters operating with the Boost converter topology for low and medium voltage as well as and power appliances. A categorization of bridge, semi-bridgeless, and bridgeless, in accordance with the construction characteristics, was carried out in order to unify the technical terminology. Benefits and disadvantages are described and analyzed in detail. Furthermore, a comparison performance in terms of PFC, Total Harmonic Distortion (THD), power capacity, electromagnetic compatibility (EMC), number of elements, and efficiency is included.

“…The Python interface was developed to capture and manipulate the variables of the converter's circuit provided by OpenModelica. The main motivation of this paper is to expand on the research works presented in [39,46,47]. In [39], the SBBC mathematical model was explained, showing in detail each converter's operational mode.…”

“…This system has a cascade control with an external loop to guarantee a stable DC output voltage and an internal loop to ensure that both PFC and THDi in the input AC current comply with international standards. In [46], a hybrid SMC-PI control was implemented in order to improve the PI control's performance. In the first stage, the PI internal loop for the current was changed using SMC; in the second stage, an adaptive hysteresis band was implemented instead of the PWM modulator.…”

Sliding-mode control (SMC) is a robust technique used in power electronics (PE) for controlling the behavior of power converters. This paper presents simulations and experimental results of an optimal SMC strategy applied to Semi-Bridgeless Boost Converters (SBBC), which includes Power Factor Correction (PFC). As the main contribution, the optimal coefficients of the SMC strategy are obtained using two metaheuristic approaches, namely the Genetic Algorithm (GA) and Particle Swarm Optimization (PSO). The main objective is to obtain the sliding coefficients that ensure the best converter response in terms of the input current and output voltage, both during start-up and under disturbances (including changes in load, source, and references). The fitness function to be minimized includes two coefficients, namely the Integrative Absolute Error (IAE) and the Integral Time Absolute Error (ITAE), for both the input current and output voltage. These coefficients measure the converter’s effort to follow the control references. The IAE penalizes errors during start-up, whereas the ITAE penalizes errors in the steady state. The tests carried out demonstrated the effectiveness of the GA and PSO techniques in the optimization process; nonetheless, the GA outperformed the PSO approach, providing sliding coefficients that allowed for a reduction in the input current overshoot during start-up of up to 24.15% and a reduction in the setting time of the output voltage of up to 99%. The experimental results were very similar when tuning with the GA and PSO techniques; nevertheless, tuning with the GA technique produced a better response in the face of disturbances compared to the PSO technique.
