本文介绍了一种在Ｓｉ（Ｌｉ）探测器漂移过程中的漂移电源，这种电源和其它普通电源完全不同，它主要由双向可控硅和双向触发二极管等新型器件组成，使输出直流电压从０～１０００Ｖ范围内连续可调，输出电流最大为１００ｍＡ，当硅片在漂移过程中，由于温度升高而电流增加时，漂移电压可随之下降，从而保持加在硅片上的功率基本不变，这样保证了不致造成损坏硅片现象。用此电源已成功地漂移出４０块Ｓｉ（Ｌｉ）探测器，现已投入在空间实验中使用，取得了良好而满意的效果。
This article presents a drift power supply during the Si (Li) detector drift. This power supply is completely different from other conventional power supplies. It consists mainly of new devices such as triacs and bidirectional triacs that allow the output DC voltage from 0 ~ 1000V continuous adjustable range, the maximum output current of 100mA, when the wafer during the drift, due to temperature increases and the current increases, the drift voltage can be reduced, so as to maintain the power added to the silicon is basically not Change, so as not to damage the silicon caused by the phenomenon. With this power supply, 40 Si (Li) detectors have been successfully drifted and have been used in space experiments with good and satisfactory results.
