| 摘 要： | 针对取样电阻在大功率恒流源中的作用和技术要求，在理论和实验上对取样电阻的设计原则、结构形式和材料选择方法进行了系统分析。对水冷式和自冷式两种结构形式的大功率恒流源取样电阻进行了比较研究，实验结果表明:相比于水冷式取样电阻情形，装配自冷式取样电阻的恒流源主要技术指标得到明显改善，输出电流失稳度降低2/3，纹波系数由2.7%降低到2.3%，使用寿命提高10倍以上。

| Abstract: | According to the function and technical requirements of the sampling resistor in high power constant-current source, the design principle, structure and choice criterion of the material of the resistor were systematically summarized based on theoretical analysis and experimental study.The water-cooling and self-cooling sampling resistors of high power constant-current source were compared. The experimental results show that, compared with water-cooling sampling resistor, the self-cooling sampling resistor improves the stability of the constant-current source three times, reduces the ripple coefficient from 2.7% to 2.3%, and increases the life time more than 10 times. |
