Optimizing the Series Connection of Thermal Converters for AC-DC Current Calibration - Experimental Verification

Connecting thermal current converters (TCC) in series for calibration of current ac-dc difference, attention has to be paid to the various current leakages that may occur. Calculations indicate leakage error less than 2*10
^-6
at frequencies up to 100 kHz. Measured values show that error contributions are less than 1*10
^-6
at 100 kHz, which is well below the predicted value
