Abstract :
The ac-dc transfer difference at low frequencies of thermal converters for higher voltages with planar multijunction thermal converters (PMJTCs) and series resistors has been determined by using only the established linear change of the low-frequency ac-dc current transfer difference of the PMJTC with input power. Uncertainties of less than 1 muV/V are achieved up to 1000V
