Overview of power loss measurement techniques in power electronics systems

Measuring power loss accurately is of great importance for power electronics systems design and for assessing system performance and reliability. This paper reviews various power loss measurement techniques in power electronics systems. A brief overview of electrical methods for loss measurements is given. Calorimetric methods, the most accurate of all instruments for measuring power loss, are described along with their implementations. The pros and cons of various techniques are discussed and compared for estimating the losses in integrated power electronic modules (REM).
