Abstract
A new thermal power comparator of audio frequency has been developed, which is essentially a double bridge-type multipliers comprlsed of two multijunction thermal converters, containing two heaters. Together with a precision inductive voltage divider and current transformer for extending voltage and current range, the comparator enables establish a high precision power standard with ac-dc transfer error less than 15 ppm in audio frequency range.
