Abstract
Although the device temperature is one of the most critical parameters in the dimensioning of
an inverter, experimental studies focusing on the virtual junction temperature (Tvj) in running
inverter are scarcely found. In this work the feasibility of four different practical methods is
compared. Special focus is set on routines with a high time resolution that enables tracking of
the time-dependent-temperature during one period of the sinusoidal output current. Details of
the procedures are explained and compared with simulations.
