1983年我们制作了一台由机组供电的晶体管稳流电源,取代原苏制BT-4稳流装置,作为ЭГ-2.5质子静电加速器分析磁铁的激磁电源。主要技术指标为:(1)额定输出直流电压100 V;(2)额定输出直流电流30 A;(3)电流调节范围0—30 A;(4)电流稳定度为±1.4×10~(-5)(当负载变化±10%时),±1.0×10~(-5)(当电网电压变化±10%时);(5)长时间漂移为2.3×10~(-5)/h,5.26×10~(-5)/8 h;(6)电流纹波为8.7×10~(-5)。 相似文献

混沌背景下信息处理的A/D转换器原理与实现研究 总被引:1,自引:0,他引:1
以混沌系统的初值敏感性为基础,从倒锯齿映射出发,按照符号动力学原理,建立符号序列空间,通过计算两条轨道空间距离来进行A/D转换;用恒流式混沌电路设计了该A/D转换器,其中的敏感元件采用模拟电容以利于器件集成化;通过分析电路的优点和存在的问题,指出这种理论和方法还有待完善.实验结果表明,这种构思具有电路简单、分辨率和灵敏度均较高、非线性误差较小和适应能力较强的特点. 相似文献

A proposal for the design of a pulsing reactor operating on light water and enriched uranium is given in this article, and the method of calculating the physical and thermal parameters of such a reactor are indicated. It is shown that when certain definite conditions are established very stable heat generation during the neutron pulses may be obtained. In the version of a pulsating reactor discussed here, the calculations indicate that it is possible to obtain over 5 Mw power with an average thermal neutron flux greater than 1014 neutrons/cm2· sec and a maximum neutron flux (during neutron pulse) of approximately 1017 neutrons/cm2 · sec in the reactor core.The author takes this opportunity to express gratitude to Academician I. V. Kurchatov for his interest in this work. The author is also grateful to U. N. Zankov for his discussion of the conclusions, and to A. K. Sokolov for his participation in a number of calculations. 相似文献
