    Abstract

    Magnetic components are usually assumed relatively reliable in power electronic converters. Nevertheless, with the trend for ever-increasing power density, planar magnetics may need to be designed with reduced margins in terms of thermal and insulation. Wear out or even failure of magnetic components may become an issue in extreme design and operation scenarios. This paper presents the first observations in degradation testing of planar magnetics at high temperatures. It serves to investigate the change of various parameters and identify possible ones as the health indicators of magnetic components for power electronic applications. The degradation testing and characterization results are presented and interpreted.
