基于数控稳压电路的便携仪表电源研制

Development of Portable and Digital Controlled DC Stabilized Power Source for Instruments

摘要: 针对仪表进行调试前，电路供电要求复杂多变，常规可调电源体积大、重量重、需要外部供电等问题，提出一种面向仪表调试的便携电源。这种电源利用锂电池组储能，工作时通过数控稳压电路调节输出，达到可调电压或电流供电。本文将便携电源应用于仪表调试，结果表明，调试过程接线快捷，准备时间短，移动方便，且满足仪表调试的工作要求。

Abstract: Aiming at the problem about the complexity and diversity of power supply for instruments, the large size and heavy weight of normal adjustable DC power supply, a kind of portable power supply for debugging of instruments is proposed. The power supply stores energy in lithium batteries, output adjustable voltage or current with digital controlled circuitry. In this paper, portable power supply is applied to instrument debugging. The results show that on the debugging process, wiring is fast, preparation time is short, movement is easy, and it meets the requirements of instrument debugging.
