Time Resolved In Situ Tvj Measurements of 6.5kV IGBTs during Inverter Operation

چکیده
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.

Five-Level Common-Emitter Inverter Using Reverse-Blocking IGBTs
In a high switching frequency operation of current-source inverter (CSI), a conventional way to obtain unidirectional power switches is by connecting discrete diodes in series with the high speed power switches, i.e. power MOSFETs or IGBTs. However, these discrete diodes will cause extra losses to the power converter. This paper presents experimental test results of high switching frequency fiv...
