Modern semiconductors like GaN and SiC enable high efficient power conversion and provide superior switching behavior. For achieving high efficient converter designs, reliable data concerning losses is vital. Due to the high voltage and current slew rates during switching, the conventional double pulse test cannot be beneficially applied when using GaN to gain results concerning switching losses. Thus, this paper proposes a novel procedure to estimate switching losses by means of thermal measurements. A characterization of the test setup using DC currents links the occurring device temperatures during switching operation to power losses. First measurements prove the applicability of the procedure to a 100 V GaN device.
