In order to solve problems of long time charging, low efficiency, overcharging and undercharging caused by the conventional battery charging methods, a new power supply is designed. The new power supply chooses the full bridge converter as the main circuit, taking ADuC814 microcontroller and SG3525 as the master control chips, and adding into the intelligent management. Prototype test waveform and experimental results demonstrate that this intelligent power supply not only has high stability, but also is time-saving;and its output voltage ripple is below 100 mV, and the efficiency is above 85%, which can achieve good practical value.
