6.2 Typical Switching Waveforms
Switching waveforms during hard switching of the semiconductors are measured with an oscilloscope using the standard
double-pulse test procedure.
Figure 18 shows the turn-on switching transient, while in Figure 19 , the turn-off switching
transient is depicted.

6.3 Typical DESAT Protection Performance
The functioning of the DESAT protection is obtained by performing the direct short circuit on one of the bridge legs. Figure 20
shows the results of this measurement.
