Abstract
Heater-thermopile isolation of planar, thin film, multijunction thermal converter decreases with frequency. This causes an interaction with the measurement circuit, resulting in increased error of measurement of its AC-DC transfer difference. The paper discusses the sources of this error and methods of its reduction, illustrated by results of experiments.
