[en] A drift power supply for Si(Li) detector has been developed, which is completely different from many other power supplies for common use. The drift power supply provides the most extensive useful voltage range of 0∼1000 V, and is continuously adjustable. It has good stability, constant power and compact structure, and the maximum output current is 100 mA. Since SCR's (silicon-controlled-rectifier) with trigger diodes and other new components are adopted and a power restriction circuit is considered in design, so during the operation when the resistance rate of silicon pieces in drifting process changes with the temperature, the power remains constant. The lower the resistance rate when the temperature raises, the higher the drift current and lower the voltage on the silicon piece. On the contrast, the higher the resistance rate when the temperature lowers, the lower the drift current, and higher the voltage on the silicon piece. Forty pieces of Si(Li) detector have been successfully drifted by using this drift power supply
