Down hole power system of high-resolution induction logging tools

文章研究了高分辨率感应测井仪的井下电源系统,包括整流滤波和稳压电路。电路中选用了高精度的器件来减小电路的噪声影响,稳压电路采用了串联型线性稳压方式,具有输出电压稳定、输出电阻小等特点。通过电路调试,井下电源系统的各项指标符合设计要求。

This paper studies on the down hole power system of the high-resolution induction logging tool, includes the rectifier filter and regulator circuit. High-precision components selects in the circuit to reduce the noise of the circuit, and the voltage regulator circuit uses series linear regulator whose features is stable in output voltage and small in output resistance. Through the circuit debugging the indicators of underground power system meet the design requirements.
