超级电容充电策略研究

超级电容是一种绿色环保的电化学电容器,其充电过程受内阻和有效电容等诸多因素的影响,对其充电方法进行研究,在以后的工程应用中具有重要的意义。采用二阶段充电模式对其充电,控制电路以TMS32芯片为核心,通过检测超级电容的端电压,送入DSP进行分析和处理,得到相对应的PWM控制信号来控制主回路开关管（IGBT）的开通和关断,从而改变充电电流的大小,实现超级电容的智能充电。

Charging Strategy Research of Super Capacitor

The super capacitor is a kind of green environmental protection electrochemical capacitor, the charging process is affected by inner resistance and the effective capacitance and other factors, researching the charging method has significance in its subsequentengineering application. In this paper, the intelligent charging of a super capacitor was realized by two stage charging mode. The control circuit took a TMS32 chip as the core, which detected the super capacitor voltage and put the voltage signals into the DSP toanalyze and process, the processed PWM control signal was used to control the main circuit switch （IGBT） turning on or off, thereby changing the size of the charging current to achieve the intelligent charging of the super capacitor.
