Modeling and Control of a Three-Phase Interleaved Buck Converter as a Battery Charger by El Nouha Mammeri, Oswaldo Lopez-Santos, Abdelali El Aroudi, Jure Domajnko, Natasa Prosen, Luis Martinez-Salamero

“…The control strategy consists of a multiple-loop controller in cascade configuration to implement the constant-current constant-voltage (CC-CV) protocol for the fast charging of an electric vehicle (EV) battery. To compensate for the inherent asymmetric distribution of the current between the phases, the first control loop (inner loop) is dedicated to implement the democratic current sharing technique, while the two outer loops constitute a seamless controller, which allows a soft transition from CC mode to CV mode when charging the battery. …”

Numerical Design of Ultrathin Hydrogenated Amorphous Silicon-Based Solar Cell by F. X. Abomo Abega, A. Teyou Ngoupo, J. M. B. Ndjaka

“…Secondly, to explore the impact of certain properties of the solar cell, investigations focus on the study of the influence of the intrinsic layer and the buffer layer/absorber interface on the electrical parameters (JSC, VOC, FF, and η). The increase of the intrinsic layer thickness improves performance, while the bulk defect density of the intrinsic layer and the surface defect density of the buffer layer/i-(a-Si:H) interface, respectively, in the ranges [109 cm-3, 1015 cm-3] and [1010 cm-2, 5×1013 cm-2], do not affect the performance of the ultrathin a-Si:H-based solar cell. …”
