摘要
设计了一种BUCK型恒流源,给出其电路原理图并进行了分析,借助Saber软件对电路进行了仿真,将仿真结果与实验结果进行了比较;针对输入特性测试的要求即负载固定不变的情况下,改变交流输入电压的大小,分析电流的变化情况。结果表明,在输入电压变化的范围内,电流恒定不变。
A BUCK-type constant-current power is designed. Firstly, the schematic diagram of the power supply is designed and analyzed. Secondly, the circuit is simulated and analyzed based on Saber, and the simulation and experiment results are compared. Finally, for the experimental requirements of input characteristics （with the load constant）, the value of the AC input voltage is altered and the change of the current is analyzed. The results show that the current keeps constant when the AC input voltage changes.
