本文介绍了一种使用无功电阻分压器（RVD）将低压AC-DC转换标准范围从100 mV扩展到2 mV的方法。为RVD选择低比率，以避免放大器的热传递标准范围的变化。这种方法的优点是多结热转换器可以用作参考标准。在10 Hz-1 MHz的频率范围内，用RVD在2 mV下测定的AC-DC传递差的结果与使用微电位计的结果吻合良好。
This paper describes a method for extending the range of low-voltage ac-dc transfer standards from 100 down to 2 mV using nonreactive resistive voltage dividers (RVDs). A low ratio is chosen for the RVD to avoid variations in the ranges of the thermal transfer standards with amplifiers. The advantage to this method is that a multijunction thermal converter can be used as a reference standard. The results of ac-dc transfer differences determined by RVDs at 2 mV were in good agreement with the results from using micropotentiometers in the frequency range of 10 Hz-1 MHz.
