Abstract :
A new automatic system for measurements of the voltage dependence of range resistors for AC-DC thermal converters, has been set up. Using this system, high precision measurements of the difference between the voltage dependence of the impedance and that of the DC resistance are performed. These measurements have shown that this difference does not fully explain the variation of the AC-DC transfer difference.
