摘要：
A new automated ac-dc difference comparator has been designed at the National Research Council of Canada (NRC). It has been used to intercompare the group of multijunction thermal converters which forms the NRC low-frequency 10 Hz to 10 kHz standard. Reduction of calibration uncertainties in the 10 kHz to 100 MHz frequency band has been achieved by improvements in design and theoretical calculations of the calorimetric TVC reference standards.
