为物探仪器改进的稳压电路

IMPROVEMENTS IN VOLTAGE-STABILIZING CIRCUITS FOR GEOPHYSICAL APPARATUS

本文介绍了几种供物探仪器使用的、经过改进的稳压电路,其中包括小功率、中功率、大功率和具有自动恢复功能的过流保护电路.这些电路结构简单,无需辅助电源,可靠性高,稳压性能比一般的稳压电路要好.

In this paper, the author presents several improved voltage-stabilizing circuits for geophysical apparatus. Among them, there are several overcurrent protection circuits which have the function of automatical resetting and can be used in wide-range power brackets. These circuits are very simple in structure and needn’t any subsidiary power supply. All of them have a very good reliability and are superior to the circuits in common use in voltage-stabilizing.
