摘　　要：电压交直流转换标准是电学计量常用标准之一,通过电压交直流转换标准将交流电压和已知直流电压进行比较,可以将交流电压最终溯源到直流电压上。介绍了常用的几种电压交直流转换标准的原理和校准方法。对在毫伏级量程校准交直流转换标准的方法、步骤和主要不确定度来源进行了简要分析和阐述,给出了采用10∶1自校准感应分压器时在系统设计中应注意的问题和环节。在此基础上,还阐述了在交直流转换校准时数据处理的方法和公式。Voltage AC-DC converter standard is one of the common electricity metering standards ,compared with voltage AC-DC converter standard ,AC voltage can ultimately be traced to DC voltage ,which has a higher precision . This article describes several common voltage AC-DC converter standard principles and calibration methods .Calibration methods in the millivolt range of AC-DC converter standard ,procedures and major sources of uncertainty are briefly analyzed and explained ,this paper also gives a system design of 10∶1 voltage divider self-calibration .On this basis , the paper also describes the AC-DC converter calibration data processing methods and formulas .
