Review of magnetics losses measurement in power converter

The losses of magnetics account for a relatively large proportion of the total loss of power converter, the accurate estimation of which is critical to the efficiency of power converters. The measurement technology is the foundation of all research on the magnetics losses, which is also the most direct and effective means to evaluate the magnetics losses. Available magnetics losses measurement techniques were reviewed. The principle, characteristics and application of various calorimetric methods and electrical measurement methods were compared and analysed. Finally, the development trends and research directions of the magnetics losses measurement technology were envisaged.
