基于ATmega16单片机的智能快速充电机设计与研究

Research and design of intelligent rapid charger based on ATmega16

介绍了利用产生定频PWM脉冲的集成芯片SG3525AN作为电源核心驱动芯片,外加ATmega16单片机扩展外设的智能快速充电机。该充电机采用国内先进的高频开关电源技术及智能充电技术,弥补了工频充电机的缺点,主电路采用进口功率MOSFET管,保证了整机的可靠性和稳定性,大大延长了蓄电池的寿命,并且完全做到了免人值守的自动工作状态。

A sort of intelligent rapid charger was introduced. Integrated chip SG3525 AN was adopted which could produce the fixed frequency PWM pulse as the power core driver chips, and ATmega16 expand peripherals.Domestic advanced high-frequency switching power supply technology and intelligent charging technology were adopted to make up for the shortcomings of AC charger. The imported power MOSFET tube was adopted to ensure the reliability and stability of the whole machine, then the life of battery was greatly prolonged, and automatic working state of no man on duty was completely reached.
