日本国家计量研究所开发了新的薄膜量程电阻器，以重新建立100-1000 V范围内、1-100 kHz频率下的AC-DC电压传输标准。在早期的研究中，在300 V以上的升压过程中观察到了交流-直流传输差的电压依赖性。这种电压依赖性的一个可能原因是由于焦耳加热引起的温度升高，这可能导致电阻器的电阻发生变化，以及电阻器涂层中介电损耗的温度依赖性。为了降低电阻的电压依赖性，本文在氮化铝衬底上直接制作了新型薄膜加热器，以防止热量在量程电阻中积累。通过测量不同量程电阻器之间的阻抗差来评估电压依赖性。在100至1000 V的升压过程中，实现了可忽略的电压依赖性。
New thin-film range resistors have been developed at the National Metrology Institute of Japan, to re-establish ac-dc voltage transfer standards in the 100-1000-V range at frequencies of 1-100 kHz. In earlier studies, the voltage dependence of the ac-dc transfer difference was observed during step-up procedures above 300 V. One of the possible reasons for this voltage dependence is the temperature rise due to the Joule heating, which may cause changes in the resistance of the resistor, as well as the temperature dependence of the dielectric losses in the resistor coating. In this paper, to reduce the voltage dependence, new thin-film heaters were directly fabricated on an aluminum nitride substrate to prevent heat from accumulating in the range resistor. The voltage dependence was evaluated by measuring the differences in impedance among various range resistors. Negligible voltage dependence in the step-up procedures from 100 to 1000 V was achieved.
