Evaluation of low-frequency AC-DC difference of coaxially mounted thermal voltage converter

The paper describes results of measurements of AC-DC transfer difference of a coaxially mounted, thermal voltage converter. Results of experiments, conducted in the 1 kHz to 1 MHz frequency range, are compared with results of simulations, using a simplified model of the converter. AC-DC transfer difference contributions, originating in the input connector and elements of the coaxial enclosure, are presented.
