基于反馈控制的恒流型电子负载的实验研究

Experimental Research of CC E-load Based on Feedback Control

给出了基于反馈控制的恒流型电子负载的结构框图,分析了控制原理,重点介绍了比例积分(PI)调节器参数的工程设计方法。对功率场效应晶体管的使用进行了简单介绍,设计了实际的恒流型电子负载电路,实验结果验证了本电路结构简单、成本低廉且具备了一定的快速性、稳定性和抗扰性。

The structure block diagram of the CC E-load based on feedback control is given in this paper,which analyzes the control principle and mainly introduces the technical design method of the PI adjuster parameters. It simply introduces how to use the power MOS FET. An actual CC E-load is also designed. The experiment results show that the circuit has a simple structure,low cost, and the performance of rapidity,stability and interference rejection.
