Calorimetric Measuring Systems: Characterizing High-Frequency Power Losses in Power Electronic Components and Systems

This paper discusses the calorimetric measuring system. The calorimetric principle is one of the most promising methods for accurate power measurements. A calorimetric wattmeter provides a useful tool for use in the developments of new, energy-efficient, electrical components for industrial and consumer products. Power measurements can be performed with an accuracy of 0.2% of full-scale deflection using the proposed calorimetric measuring method.
