CHARGING SYSTEM AND METHOD OF BATTERY |
| 摘要 |
A charging system and method of a battery are provided. The charging system includes a PFC (power factor correction) converter that converts alternating current input voltage into direct current input voltage and outputs the direct current voltage, and corrects a power factor. A DC-DC (direct current-direct current) converter varies the levels of direct current voltage output from the PFC converter and a battery is charged with the current output from the DC-DC converter. In addition, a controller is configured to adjust an output voltage of the PFC converter based on a charging voltage of the battery, which is varied by the charging and discharging of the battery. |
