Abstract
An electric load used in discharge test of super-capacitor was designed, which worked at the mode of the constant current (CC). It was mainly made up of two parts: constant current part and logic control part. The constant current source adopted CMOS integrated circuit to drive the MOSFET. When the power MOSFET worked in the constant current area, the current of drain-source did not change with voltage. The design of the logic control part was a digital circuit, which controlled the open or shutoff of the constant current unit by counter permanent. The design of the electric load is simple and affected rarely by temperature. The device can be used to test the super-capacitor, and the performance of the super-capacitor can be known better.关键词
