多用途高压直流可调稳压电源

High-voltage Direct-current Adjustable Voltage-stabilized Power Source for Multiple Usages

本文使用三端可调稳压集成电路LM317T,巧妙地控制高于其稳压值6倍以上的高压直流电源的稳定度,从而实现了提高稳压电源精度的目的,节约了大量的电子原器件,简化了电路,降低了成本,为物理实验提供了新型的电源.

Thes article provides a new-type power source for performing experiments in physics. Here three-drection adjustable and voltage-stabilizing integrated circuit(IC)LM317T is used to skilfully control the stability of high -voltage direct-current power source, which is six times higher than its stabilizing value so that the aims are realized.The degree of accuracy is improved for this high-voltage voltage-stabilized power source.A large number of electronic appliances are saved;electric circuit is simplified,and cost is reduced.
