摘　　要：直流电子负载作为一种高精度测试仪器,在电源及功率电子元器件的实验、测试、检定和老化过程中发挥着重要作用。阐述了一种直流电子负载的校准方法,旨在分析被检仪器分辨力、校准装置误差及测量重复性等的不确定度分量。通过对校准结果的评估,得出了包含因子为2的扩展不确定度,从而验证了校准方法的准确性和可靠性。As a high-precision testing instrument,DC electronic loads play an important role in the experimen-tation,testing,calibration,and aging process of power supplies and power electronic components.A calibration method for DC electronic loads is described,aiming to analyze the uncertainty components of the resolution of the tested instru-ment,calibration device errors,and measurement repeatability.By evaluating the calibration results,an extended uncer-tainty with a factor of 2 was obtained,thereby verifying the accuracy and reliability of the calibration method.
