Abstract
We have proposed a model of a thermal voltage converter(TVC) using the trans-impedance of lossy transmission line and developed a calculation program for ac-dc transfer difference of the TVC. The proposed TVC consists of a thermo-element(f) and a range resistor wire connected in series at the center of coaxial cylinder. The range resistor wire is used to extend the measurement range of the n. The calculated ac-dc transfer differences of the proposed TVC by simulation agree well with the measured values within the uncertainties. The simulated and measured values are agreed within $1{\mu}V/V$ from 40 Hz to 10kHz, within $5{\mu}V/V$ from 20kHz to 100MHz, and within $12{\mu}V/V$ from 200kHz to 1 MHz.
