Research and Development of a Supply for Deuterium Lamp High Stability and Multi-function Constant Current Power

This paper introduced a constant current power supply for deuterium lamp.It has the characteristics of high stability and multi-function.It has the current regulation of 6.5×10~(-6) and drift of 5.0×10~(-5)/H.In scientific research and production for deuterium lamps, this power supply can satisfy testing needs. When it is used together with UV Spectrophotometer, HPLC and flow injection analysis, it can be applied as deuterium lamp power supply in these instruments. If there are needs for the constant current power supply of 50-450mA in some instruments, this power supply can satisfy application needs.In this paper, the fundamental principle, circuit configurations and primary technical specifications were described briefly. Meanwhile some special problems like current regulation,output current, output trigger voltage, operating voltage and the ratio of function & price etc.were discussed。
