Fast charger for high capacity batteries |
| abstract |
A highly efficient fast charger for high capacity batteries and methods for fast charging high capacity batteries. The fast charger preferably comprises a rectified AC input of single or preferably three phases, with an optional power factor corrected input, minimally filetered with high frequency, high ripple current capacitors, which is switched with a power switching circuit in the 'buck' configuration into an inductor/capacitor output filter. Metallized film capacitors are employed, to minimize the rectified 360 Hetz AC component filtering while providing transient switch protection and ripple current requirements for the buck regulator, to provide a high current fast charger with substantially improved power factor. High power, high frequency switching with minimized output filter size provides a highly filtered DC output. The fast charger is adapted to be constructed in a modular design for simple maintenance. |
