high voltage gain boost converter based on three state commutation cell for Battery charging using pv panels in a single conversion stage
IEEE Transactions on Power Electronics, 2014Co-Authors: Luiz H. S. C. Barreto, Paulo P. Praça, Demercil S. Oliveira, Ranoyca N.a.l. SilvaAbstract:This paper presents a novel high-voltage gain boost converter topology based on the three-state commutation cell for Battery charging using PV panels and a reduced number of conversion stages. The presented converter operates in zero-voltage switching (ZVS) mode for all switches. By using the new concept of single-stage approaches, the converter can generate a dc bus with a Battery Bank or a photovoltaic panel array, allowing the simultaneous charge of the batteries according to the radiation level. The operation principle, design specifications, and experimental results from a 500-W prototype are presented in order to validate the proposed structure.

Single stage high voltage gain boost converter with voltage multiplier cells for Battery charging using photovoltaic panels
Conference Proceedings - IEEE Applied Power Electronics Conference and Exposition - APEC, 2012Co-Authors: Luiz H. S. C. Barreto, Paulo P. Praça, Gustavo A.l. Henn, Ranoyca N.a.l. Silva, Demercil S. OliveiraAbstract:This paper presents a non-isolated high frequency DC-DC converter, which integrates a Battery charger, photovoltaic panels, and a high voltage gain boost converter in a single conversion stage with soft-switching characteristic. The proposed topology uses voltage Multiplier Cells (MCs), leading do high voltage step-up. Also, the bidirectional behavior admits the DC bus to be generated via Battery Bank, or photovoltaic panels, or both, depending on the insulation condition. At last, experimental results validate the proposed topology, proving its effectiveness.

optimal sizing of small wind Battery systems considering the dc bus voltage stability effect on energy capture wind speed variability and load uncertainty
Applied Energy, 2012Co-Authors: Juan M Lujanorojas, Rodolfo Dufolopez, Jose L BernalagustinAbstract:In this paper, a mathematical model for stochastic simulation and optimization of small wind energy systems is presented. This model is able to consider the operation of the charge controller, the coulombic efficiency during charge and discharge processes, the influence of temperature on the Battery Bank capacity, the wind speed variability, and load uncertainty. The joint effect of charge controller operation, ambient temperature, and coulombic efficiency is analyzed in a system installed in Zaragoza (Spain), concluding that if the analysis without considering these factors is carried out, the reliability level of the physical system could be lower than expected, and an increment of 25% in the Battery Bank capacity would be required to reach a reliability level of 90% in the analyzed case. Also, the effect of the wind speed variability and load uncertainty in the system reliability is analyzed.

Also, the effect of the wind speed variability and load uncertainty in the system reliability is analyzed. Finally, the uncertainty in the Battery Bank lifetime and its effect on the net present cost are discussed. The results showed that, considering uncertainty of 17.5% in the Battery Bank lifetime calculated using the Ah throughput model, about 12% of uncertainty in the net present cost is expected. The model presented in this research could be a useful stochastic simulation and optimization tool that allows the consideration of important uncertainty factors in techno-economic analysis.
