Tubes à rayons X Résumé : This paper presents the analysis and novel controller design for a hybrid switched-capacitor bidirectional dc/dc converter. Features of voltage step-down, step-up, and bidirectional power flow are integrated into a single circuit. The novel control strategy enables simpler dynamics compared to a standard buck converter with an input filter, good regulation capability, low electromagnetic interference, lower source current ripple, ease of control, and continuous input current waveform in both modes of operation (buck and boost modes).

Power-electronics-based solutions for plug-in hybrid electric vehicle energy storage and management systems / Amjadi, Zahra in IEEE transactions on industrial electronics, Vol. 57 N° 2 (Fevrier 2010) 

Public ISBD [article]  in IEEE transactions on industrial electronics > Vol. 57 N° 2 (Fevrier 2010) . - pp. 608 - 616 Titre : Power-electronics-based solutions for plug-in hybrid electric vehicle energy storage and management systems Type de document : texte imprimé Auteurs : Amjadi, Zahra, Auteur ; Williamson, Sheldon S., Auteur Article en page(s) : pp. 608 - 616 Note générale : Génie électrique Langues : Anglais (eng) Mots-clés : Battery  storage  Capacitors  Electric  vehicles  (EVs)  Energy  management  Energy  storage  Power  electronics  Road  vehicles Index. décimale : 621.38 Dispositifs électroniques. Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : Batteries, ultracapacitors (UCs), and fuel cells are widely being proposed for electric vehicles (EVs) and plug-in hybrid EVs (PHEVs) as an electric power source or an energy storage unit. In general, the design of an intelligent control strategy for coordinated power distribution is a critical issue for UC-supported PHEV power systems. Implementation of several control methods has been presented in the past, with the goal of improving battery life and overall vehicle efficiency. It is clear that the control objectives vary with respect to vehicle velocity, power demand, and state of charge of both the batteries and UCs. Hence, an optimal control strategy design is the most critical aspect of an all-electric/plug-in hybrid electric vehicle operational characteristic. Although much effort has been made to improve the life of PHEV energy storage systems (ESSs), including research on energy storage device chemistries, this paper, on the contrary, highlights the fact that the fundamental problem lies within the design of power-electronics-based energy-management converters and the development of smarter control algorithms. This paper initially discusses battery and UC characteristics and then goes on to provide a detailed comparison of various proposed control strategies and proposes the use of precise power electronic converter topologies. Finally, this paper summarizes the benefits of the various techniques and suggests the most viable solutions for on-board power management, more specific to PHEVs with multiple/hybrid ESSs.
