Development of a thermal voltage converter with calculable high‐frequency characteristics

A thermal-voltage converter for high-frequency (HF-TVC) AC–DC transfer standard has been developed. The HF-TVC was designed such that the frequency characteristic is calculable from the shape and dimension of the input circuit. A new multi-junction thermal converter element (JSTC04) has been developed, which has a simple and straight heater configuration to minimize the parasitic impedances in the input circuit. The AC–DC difference of the HF-TVC was evaluated by two independent methods, with agreement better than 7 µV/V up to 1 MHz. © 2011 Institute of Electrical Engineers of Japan.
