Outline of Final Research Achievements

We have developed new thin film multijunction thermal converters to realize a reliable AC power standard. At present, the AC power standard is derived quantity composed of voltage, current and phase. Although this method is widely used, it is difficult to extend the range of AC power standards when AC voltmeters, AC amperemeters, phase meters are used as references. In this study, the power standards have been established based on the thermal converters, which are capable of extending the range of AC voltages, AC currents and their frequencies. The AC power values obtained from the new method are in good agreement with values obtained from the conventional method.
