This digest proposes an individual cell voltage equalizer using selective two current paths for series connected lithium-ion battery strings. In the proposed equalizer, a central equalization converter is shared by every battery cells through the cell selection switch, instead of a dedicated charge equalizer for each cell. The central converter is utilized as a controllable current source by a modified...
Nowadays, technologies are providing the mobile terminals with much more powerful computational abilities. Such improvement made it possible to run many complex applications on mobile devices. However, many of these new applications are also resources demanding. Lacking sufficient resources would cause performance failures and impact negatively on the users' quality of experience. In order to improve...
The charge equalizer design for a series connected battery string is very challenging because it needs to satisfy many requirements such as implementation possibility, equalization speed, equalization efficiency, controller simplicity, size and cost issues, voltage and current stress, and so on. Numerous algorithms and circuits were developed to meet the above demands and some interesting results...
This paper proposes a modularized two-stage charge equalization converter for a series-connected lithium-ion battery string in an HEV. In this paper, the series-connected battery sting is modularized into M modules, and each module has K cells in series. With this modularization, low voltage stress on the electronic devices can be achieved. A two-stage dc-dc converter with cell selection switches...
In this paper, a charge equalization converter with parallel-connected primary windings of transformers is proposed. The proposed work effectively balances the voltage among Lithium-Ion battery cells despite each battery cell has low voltage gap compared with its SOC. The principle of the proposed work is that the equalizing energy from all battery strings moves to the lowest voltage battery through...
Cold cathode fluorescent lamp (CCFL) has been used for a source of light on LCDs, and external electrode fluorescent lamp (EEEFL), flat fluorescent lamp (FFL), field emission lamp (FEL) including LED is actively progressing application for other source of light. This paper used EEFL that has advantage for decrease inverter round figures, because is advantageous to multi lamp drive, transformer decrease...
