应用于超级电容器的数控恒流源

摘要

In order to research the charging performance of super-capacitors,a constant current test system which is based on microcontroller is designed.The author uses a program-controlled constant current source which focuses on high-power MOSFET and analyzes the application of results.The result which tests the super-capacitor shows that the circuit has a simple structure and the current is very stable,which can be applied to the situation which requires high current.%针对研究超级电容器的大电流充电性能的目的,设计了一种基于单片机控制的恒流测试系统。笔者采用大功率MOSFET设计的恒流源以及对应用效果进行了分析。通过对实际超级电容器进行测试,结果表明：该电路具有结构简单,电流稳定性强,并且可应用于大电流的场合下。
