Contents I. INTRODUCTION
The need of a quantitative knowledge of power loss in any power electronics system is self-evident. Due to the increasing use of power electronics in a wide range of applications, power loss measurement with high accuracy is of great importance in the design process to assess system performance and optimize design characteristics. Driven by recent advances toward integration, higher densities and higher operating frequencies in power electronics systems, accurate estimates of power losses become more important for proper thermal management and to ensure reliable operation. Although sophisticated numerical modeling methods are often available to predict power losses, validity of the models need to be verified experimentally, especially where complex loss mechanisms exist in some parts, for instance magnetic materials for power conversion.
