| Abstract |
Active clamping is one major security function of an IGBT driver. Transil diodes are commonly
used. This paper details the investigation of an original solution without such diodes. A charged
capacitor in series with a fast diode is used. Clamping voltage is continuously adjustable.
Experimental results are presented. |
