直流稳压电源现场检定装置的研究

Study on Calibration Equipment for CD Voltage Stable Source

本文针对直流稳压电源检定中被检测设备笨重难搬移、检测设备数量多、检测环境要求高,不便于开展现场检测等困难,设计了一种便携式现场检定装置。该装置采用Atmega64单片机、高精度精密电阻、mosfet电子开关等技术,对电源调整率、负载调整率和纹波电压测量等测试技术进行电路搭建和样机实验,实现了直流稳压电源自动、半自动测试。

For the problem of CD Voltage Stable Source calibration condition： hard moving,a large number of work,strict testing environment,this paper studied the portable equipment. This equipment used the technology of low-cost AVR Atmega64 signal-chip microcomputer,high precision resistance and Mosf electronic switch etc..Test about power regulation,load regulation and ripple voltage,then complete a full prototype,and the results of dates show that the equipment can be used to automatic or semi-automatic calibration.
